Applications & Technology (A&T) is a key conference at CLEO: 2014, exploring the evolution of newly discovered technologies previously reported in CLEO: Science & Innovations as they are perfected and further developed to meet system and application requirements. New components, optoelectronics, and laser systems are demonstrated in real-world environments where innovative commercial technologies emerge.

Yu Chen, University of Maryland, Program Co- Chair provides an overview of this year’s A&T symposium and paper highlights.

CLEO Team:

Discuss the exciting lineup of symposia that are A&T related? What are some of the hot topics being covered?

Yu Chen:

This year we have organized a series of exciting symposia. The first two are focused on biomedical applications. The first one is Advances in Neurophotonics, organized by Drs. Nick Iftimia and Jin Kang. This symposium highlights the photonics technologies that enable mapping of brain function.  This is an important research area as highlighted by President Obama’s recent BRAIN Initiative. We have invited leaders in this field to share their frontier research. Topicscovered include optical coherence tomography and multi-photon microscopy for neuroimaging, high-resolution imaging of brain networks and diseases, and optogenetics.

The second area of application is Molecular Imaging, which is an interdisciplinary area intersecting photonics technology and molecular medicine, with great potentials for early disease detection and personalized treatment. This year’s symposium, organized by Drs. Xavier Intes and Ali Azhdarinia, contains two sessions: one focuses on novel optical molecular imaging techniques, including near-infrared fluorescence imaging, Cerenkov radiation imaging, and photoacoustic imaging. The other session focuses on molecular probe development and clinical translation. The speakers are renowned scientists, clinicians, and industrial leaders that set the trend in this field.

The next two symposia are more technology oriented. The first one is Novel Light Sources and Photonic Devices in Optical Imaging, organized by Drs. Charles Lin, Nick Iftimia, and Ben Vakoc. This symposium highlights the advanced development of novel light sources and photonic technologies that enable biomedical imaging. Topics include novel light sources for nanophotonics-based OCT, as well as deep tissue multiphoton imaging and manipulation.

The next symposium has similar theme, but more focuses on Ultrashort Pulse Laser TechnologiesOrganizedby Drs. Ilko Ilev and Emma Springate, this symposium highlights the recent state-of-the-art development in ultrafast laser technologies for biophotonics and nanobiophotonics. Topics include ultrafast compact fiber lasers; tunable ultrafast visible, near- and mid-IR lasers; plasmonic nanobuble based integrated theranostics, and ultrafast laser induced ion beams for proton therapy.  

The next hot topic is Optofluidic Microsystems, organized by Drs. Ian White and Andreas Vasdekis. This symposium aims to highlight emerging trends in optofluidics and their application in microsystems.  This year’s program will feature an overview of the last ten years of optofluidics by one of the founding fathers of the field, Dr. Dmitri Psaltis, and will also project into the future by talks from current leaders in the field. Topics include optofluidic lasers and resonators, optofluidics for energy, and optofluidic particle manipulations.

CLEO Team:

What exciting papers did you receive for Applications & Technology?

Yu Chen:

We have a large affluence of papers for the light sources, resulting from the success of last year’s symposium on novel light sources. We also have papers focused on Neurophotonics, as stimulated by this year’s symposium. Our program includes new developments in OCT, multiphoton microscopy, and photoacoustic imaging, as well as clinical translation. Some of the example hot topics include adaptive optics for ophthalmology, point of care devices based on smart phones, minimally-invasive imaging technologies for disease diagnosis and therapy guidance, endomicroscopy, as well as multi-modal imaging combining OCT with fluorescence/confocal.

CLEO Team: Thank you

The CLEO Conference, sponsored by APS/Division of Laser Science, IEEE Photonics Society and the Optical Society received record-breaking submissions this year. The Conference takes place in San Jose, CA, USA, 8-13 June 2014.

The application of adaptive optics techniques–namely, optical wavefront shaping and phase modulation–to correct aberrations arising from highly scattering and disordered media holds tremendous promise for in vivo fluorescence imaging of biological tissue, and in particular the functional imaging of neural circuits. This topic has experienced an explosion of research activity in recent years, driven in large part by funding and interest from the BRAIN initiative, the Presidential focus aimed at mapping and unlocking the inner workings of the human brain. Following previous Incubator meetings in Optogenetics and Adaptive Optics, the organizers see today’s meeting as a natural next step.

Since its successful and effective arrival in 1967, the Conference on Lasers and Electro-Optics (CLEO) has emerged as one of the biggest leading platforms for the researchers to be updated with recent progress in research and technology, especially with the latest worldwide advancements in optics and laser science. During such a long journey, CLEO has maintained the international prominence through its tradition of unparalleled and long standing excellence and leadership in showcasing the most significant scientific research milestones from laboratory to marketplace. Like every year, CLEO: 2014 (8-13 June in San Jose, CA, USA) is  getting ready to show its real glamour and activities for downtown san josethe optics researchers all around the world.

Just a few words to introduce myself: I am Shamsul Arafin, a postdoc working at UCLA. My research expertise is primarily in the area of semiconductor lasers, nanophotonic devices and heteroepitaxial growth of III-V on Si. I am a official blogger for CLEO: 2014. There are plenty of reasons for my excitement about this conference. These are so many that I’m not sure whether I can fit them all into this post.

First of all, CLEO: 2014 will not limit itself only to feature high quality research in the areas of: QELS- Fundamental ScienceScience & Innovations and Applications & Technology for six days, but also arrange  for special symposia, tutorials and business programming, all highlighting the latest research applications and market-ready technologies in all areas of lasers and electro-optics. In addition, this year CLEO will gather approximately 300 companies from around the globe introducing new products and demonstrating cutting-edge innovations.

Anything else? Yes, CLEO: 2014 will also provide opportunities for attendees to have some fun, catch up with fellow attendees, and meet new contacts in the industry. This is certainly a great opportunity to network and learn how to get the most out of the conference. Moreover, this event will bring together industry executives to share their business experience with young professionals and students.

Outside of the conference, one can discover the great Silicon Valley lifestyle, wide array of recreational options and experience several wonders that surround lovely Downtown San Jose, California.

You will not want to miss out on these limitless opportunities.  Looking forward to seeing you all there.

For decades biomedical optics has been touted as an ideal tool for diagnosing, monitoring and/or treating a vast array of health conditions owing to low-cost instrumentation, use of non-ionizing radiation, and incomparable sensitivity. All great characteristics; nonetheless, adoptions of optical devices in the clinic have been few and far-between. One could blame regulations, the high cost of clinical trials, and provider inertia; but these hurdles would be behind us if the optical approaches on health and healthcare costs made more more significant impact. We’re not there yet.

But we should remain unabashedly optimistic about the future of biomedical optics. Why? Read the full article.

Eric Mottay, Amplitude Systemes, France, CLEO Program Co-Chair

Submit applications-related advancements in optics & laser science


The CLEO:2014  marketing team sat down with Eric Mottay, CLEO: Applications & Technology (A&T) Program Co-Chair to gain insight on the type of research presented at the A&T conference, the scope of the meeting and the benefits of submitting cutting-edge research to this high-quality, peer-reviewed conference.

CLEO Team:   What is the purpose of Applications and Technology Conference?

Eric Mottay:  Well, the Application and Technology Conference basically builds on the core strength of CLEO, which is the high scientific content, and  explores potential new applications which have the capability to extend into the industrial or commercial domain.  So it sits really at the frontier between the science and the application development work.

CLEO Team:    What type of work is submitted to Applications and Technology?

Eric Mottay:  Well – there are broad categories of research or applied research which can be submitted to the Application & Technology.  It can be industrial development, new emerging industrial applications.  It can also relate to new fields of interest like Bio Photonics or bio applications, for instance.  And also government-funded science, large projects, everything that is basically turning pure science into the application field.

CLEO Team:  What are the benefits of presenting your work at CLEO: 2014?

Eric Mottay:  CLEO: 2014 is a unique place where science meets applications, so by going to this conference, you’ll have some indications of the future of industry while being able to interact with the people making the science that will be the basis for these future directions.  So in this sense, it’s a fairly unique forum. There is a strict review process which ensures that all papers are of really top quality and there are not that many places where in a few days you can have such a broad view of science and emerging applications.

Note: Another important benefit to add is that every accepted paper is published in OSA’s digital library, Optics InfoBase, the largest peer-reviewed collection of optics and photonics. Presented research is also submitted to IEEE’s Xplore Digital Library and indexed in Ei Compendex, Scopus and several other indexing service partners.

 CLEO Team:    When is the deadline for the call for papers?

Eric Mottay:   The deadline for the call of papers for this conference is 22 January 2014, 17:00 GMT.  So it’s not that far off, so we can only encourage scientists, industry people, and Applications-oriented professionals to submit to this exciting conference. Just go to the website and you’ll be walked through it.  It’s a fairly easy process.

CLEO Team:      Wonderful.  Will the special symposia be accepting contributions during the call for papers period?

Eric Mottay:      As part of the Application and Technology Conference, we have a number of symposia, and symposia consist both of invited papers and selected number of contributed papers.  So some of the contributed papers can be accepted in various symposia in field as diverse as microphysics, lasers for consumer electronics, government, funded projects, et cetera.

CLEO Team:    As past subcommittee chair for the industry – industrial category, can you provide examples of prior submissions that were outstanding?

 Eric Mottay:      The privilege of serving as the committee chair for the industrial applications is that you get some advance knowledge of fascinating emerging applications.  So who would have thought – who would have thought, as I saw in a recent invited conference, that cold atoms and quantum gravimeters could lead to industrial applications in oil discovery or geology, for instance, or can you imagine building tiny devices out of glass which combine optical, mechanical, electrical, and photonic functions all on a single glass chips?  That’s just two examples of what the Application and Technology Conference can provide on the latest advancements.

CLEO Team:     CLEO also holds an Expo which provides timely business programming called Market Focus. Can you tell us why this type of programming would be of interest to CLEO: Applications & Technology attendees?

Eric Mottay:   Market Focus can indicate some future large areas or large directions that the technology or the industry should follow while the application and technology builds on the scientific background to explore new ways to go into these future directions.

CLEO Team:     Thank you.

The latest innovation that has caught the imagination of the world at large is 3-D printing. As many of you may know (see the OPN article - where we found the image below) 3-D printing isn’t a single technology but several different technologies (almost all use Optics) that have been around for a decade or so. The technology has many applications, some of which make people rather nervous.

There have been discussions on the advantages of 3-D printing and the problems it may bring to us as a society. The former include immense creative freedom, the ability to make prototypes for ideas, specialist devices not suited to high volume manufacture, give a great tool to research and many more.

Yet there are problems too: what happens to the Intellectual Property (IP) if anyone can produce a 3-D copy of a device or parts? People could make weapons and use them illegally. The legal machinery in different countries probably does not have laws that explicitly pertain to additive manufacturing or 3-D printing.

This post originally appeared on Jim’s CLEO blog and is reproduced with the author’s permission.

Browsing the post deadline papers, whose sessions will run from 8:00-10:00 pm this evening, it seemed the Applications and Technology session exhibited a zoological theme.

Fly in the Ointment:

In postdeadline paper ATh5A.5, to begin at 8:48 pm, Song et al. will present work recently published in Nature on compound eye cameras that mimic the physiology of a fly’s eye. Unlike human eyes or the eyes of other vertebrates, most animals use compound eyes that have many optical units (facets), each with their own lenses and set of photoreceptors. Though compound eyes lack the sensitivity and resolution of single-lens eyes which work by forming images on a detection plane, they can have infinite depth-of-field without the need to adjust the focal length of any of the lenses. Because of this, compound eyes are very adept at calculating/perceiving relative motion. A good set of compound eyes allows the fly high-precision navigation while in flight. Digital compound eyes therefore show great promise for  micro air vehicles (MAVs) to be used for reconnaissance, sensing, and diagnostics in tight spaces (say locating people in a collapsed building, or flying inside and around machinery and other cramped environments with extreme conditions: high radioactivity, temperatures, etc).

What makes Song et al.’s work, a multi-institutional collaboration lead by the Beckman Institute of University of Illinois Urbana-Champaign, so compelling is that they make use of recent advances in stretchable electronics and hemispherical detector arrays to create a compact, monolithic, scalable compound eye.

Essentially, the collaboration fabricated a planar layer of elastomeric microlenses and a planar layer of flexible photodiodes and blocking diodes that are aligned and stretched into a hemispherical shape. Serpentine-shaped metal interconnections on the electronics aid in flexibility.

The Beckman Institute collaboration achieved near infinite depth-of-field and 160 degree field-of-view.

Crocodile Smile:

Postdeadline paper ATh5A.3, to begin at 8:12 pm, from Yang et al. of Case Western Reserve University actually addresses clinical diagnostics of human tooth decay using Raman imaging, though they image an alligator tooth to help demonstrate proof-of-concept (note all alligators are crocodiles so the cute colloquialism above is technically correct, albeit it is reaching a bit!).

Current clinical practices for dental caries (decay) lack early-stage detection. Late-stage cavities often require multiple fillings or more costly measures such as crowns, bridges, or even entire replacement of the tooth over the tooth lifetime because of the insufficiencies of x-ray and visual observation to detect lesions. If tooth lesions could be detected early, they could be remineralized at an early stage of decay, thereby preventing future costly, invasive procedures.

Yang et al. use global Raman imaging that implements a 2D-CCD array and images at a single wavenumber over full-field of view rather than point inspection over a spectrum of wavenumbers. Their Raman images show a clear border between the dentin and enamel of an alligator tooth, showing high contrast in mineral signal intensity. They also show similar images for human teeth  indicating their technique shows good promise for early clinical detection of tooth decay.

Yesterday began two days of laser-driven fusion talks punctuated by a visit to the nearby National Ignition Facilitiy (NIF) at Lawrence Livermore National Lab (LLNL) as part of CLEO Applications and Technology Special Symposium: The Path to Sustainable Energy: Laser Driven Inertial Fusion Energy.


The session began with The Physics of Laser Driven Inertial Confinement Fusion (ICF) and continued with the Technology of ICF Drive Lasers and Laser Facilities, and Optical and Nuclear Diagnostics. After the tour of NIF today, the symposium will pick up again on Thursday culminating in Future Perspective of ICF as Sustainable Energy Source.
A tutorial on ICF on the NIF website gives a cute recipe for creating the temperatures and pressures needed for fusion on earth that are only found elsewhere in our universe in stars,


Recipe for a Star:

- Take a hollow, spherical plastic capsule about two millimeters in diameter (about the size of a small pea)

- Fill it with 150 micrograms (less than one-millionth of a pound) of a mixture of deuterium and tritium

-Take a laser that for about 20 billionths of a second can generate 500 trillion Watts

-Wait ten billionths of a second

-Result: one miniature star










(Above: Figure of the hohlraum and a cross-sectional view (right) showing the fuel capsule. Figure from LLNL.)


Of course the devil is always in the details. Ignition, in which more energy is generated from the reaction than went into creating it, has yet to be achieved.  In 2009, NIF reached its laser energy goal and thought ignition would be achieved by fall of 2012.
John Lindl, of LLNL began today’s session speaking about many of these devilish details, particularly on NIF. For example, besides having the necessary peak power, the 20 ns, 500 TW laser needs to have the proper pulse shape, which is a strangely-shaped series of four pulses of tailored delay and power in order to deliver four shocks to the target at the proper intervals.


The target capsule, which may seem to be a trivial piece of the puzzle, has undergone an intense 20- year effort. Different shells of ablator materials, size, shape, density, concentricity, and surface smoothness are all key factors in a symmetric collapse (the attempt to get the correct “spherical rocket”). Lindl, spent a good portion of his talk showing diagnostics images of the collapse, and efforts to optimize the system to better ensure symmetric spherical collapse and confinement.


Other factors include whether to use direct drive (hitting the capsule directly with the many laser beams) or indirect drive (hitting a cavity called a hohlraum with the beams to generate a symmetric barrage of x-rays to initiate collapse). NIF uses a hohlraum and 192 beams. Omega in Rochester, NY uses direct drive, which accelerates more fuel to burn, potentially for better energy production (when that day comes). Beam configurations, target placement and position, and much more come into play. Of course simulation has been a key factor in design, result interpretation, and future direction. The immense effort for ICF at NIF, as well as other the facilities in the U.S. and around the world are extremely impressive and the problems are complicated, beautiful, and rich.


Laser inertial fusion energy (LIFE) is a worthy goal which could deliver a sustainable carbon-free energy source. There is no enrichment, no radioactive waste, and no worries of a meltdown; unlike fission chain reactions, when you turn “off” fusion, it is “off”. NIF is an experimental facility made to understand the physics and technology necessary for LIFE and not scalable to a power plant. Scaling ignition towards operable power plants is another direction of physics, engineering, and optics research.









(Above: Schematic of how laser ignition fusion may interface with a power plant to deliver a sustainble source of electricity. Image from LLNL.)


Currently, targets are fixed and the laser delivers a few shots a day so that experiments can be changed out, realigned, and optics and components can cool down. In a power plant facility, the hope is to use a higher-repetition rate laser to deliver 20 shots a second. Targets would be injected at speeds of greater than 100 m/s to continually burn fuel, which would heat up a low-activiation coolant of lithium-bearing liquid metals or molten salts surrounding the target in order to convert water to steam with which to turn a turbine.


Lindl said that NIF is just 2 to 3 times away from achieving ignition, meaning the output energy from the fusion reaction is one-third to one-half of the input photon energy from the laser. Though nature has provided some delays from what was previously thought, ignition is realistically around the corner. Laser ignition fusion power plants may be close as 2030.

Being an active OSA young professional comes with additional bonuses once in a while. This time, I was happily summoned as “scientific paparazzi” to sneak into one of the committee meetings for CLEO: 2013 happening in the DC metropolitan area. Digging for insider info on CLEO’s hot topics and from CLEO: 2013 committee chairs and members –  as they reviewed, scored and sessioned all the CLEO papers was the top mission.

My first impression about this conference is the vibrant energy. All the chairs and committee members were holding such high spirits. I don’t feel they came to the conference as referees to select the best papers. I feel they came to learn more and look for new inspiration.  While it can be difficult to make decisions on which papers represent the best in the field – they are there to do their job – accepting only the highest-quality papers for the CLEO: 2013 program.

My first personal encounter  with one of the Chairs was a short conversation with professor James C. Wyant,  who also served as President of OSA in 2010. As program co-chair of “CLEO: Applications & Technology,” he is very happy to see CLEO is creating a trend of applying its strength in core science into applications. This, of course, will foster more interaction between academia and industry. He is especially keen on the topics about “metrology” and “sustainable energy – laser-driven inertial fusion energy”. If you are still not aware of these two topics, I strongly advise you to check out the short course on metrology, and the tour of the National Ignition Facility (NIF) to learn more and gain a first hand experience. All of these sound very exciting.  Joining the tour allows you to have the chance to see one of the most powerful lasers in the world, and how to use it to mimic the core of the sun.  And, the metrology course will introduce you to the tabletop X-ray light source that is one of the prominent rising stars in optical science. You better grab your opportunity to attend by checking out the CLEO website now.

Professor Wyant also shared the concern about the impact of U.S. federal government’s sequester on optical science too. Although we all feel sorry about the cuts on  financial support, he is cautiously optimistic. Optical science has found its applications in many aspects of our society, and many more will come. With all of  humanity benefiting from optical science applications, we shall look for more that originate from optical science to accompany our future. Thanks to him and many other researchers, we are striving toward this goal.

Then, I was lucky to catch a few humorous and witty scientists during the lunch break. Having a meal together with Professor Christian Wetzel, Professor Mark A. Zondlo, and Dr. Max Shatalov – manager of SETi. They all serve in the session of environment/energy.  They were impressed by an increase of the number of the submitted papers. To me, it seems to make sense. With the population of Homo sapiens increasing, the Earth is barely breathing. Without our effort, we will definitely engage into an irreversible future. As a result, taking care of the environment must become our priority, and I am happy to see research that is helping to make this possible.

They also told me about some interesting topics you should not miss:

1.      Using the quantum cascade lasers for the environmental sensing: We are all very excited that QC lasers are finally portable and can be brought to the field for various applications. For example, trace gases like SO2, methane, or air pollutants are all targets under the scrutiny of QC lasers. If you are a green-oriented person, you should not miss this opportunity when you come to CLEO: 2013. In addition, we were discussing a very interesting paper in which a laser is used to probe the “particle size.” Again, if you feel intrigued about it, you just have to keep your eyes open for topics like these while wandering around in the conference center.

2.      Using UV-LED, for sterilization and water purification: This is a perfect example of how optical science is helping the humanity. UV-LED, being more compact and consuming less energy compared with traditional light sources, will probably become the main light source for food sterilization (in our discussion, UV-LED shining on strawberries was the content). The environmental impact of adopting this new light source into the food processing chain is self-evident. Cool science with a mix of practical goals – I guess this is yet another reason  why CLEO is awesome.

3.      Solar energy harvesting: How to harvest solar energy in a more efficient way is always an attractive scientific challenge for the researchers. In our short break, we touched on the topic of multi-junction cells, patterned surface — either nano or micro scales to trap more light into the solar cells, and using organic media to harvest the solar energy. Checking out the talk presented by Rebecca Jones-Albertus is a good entry point for you to delve into this domain.

In order to please the crowds of hard-core scientists, I also had a short chat with professor Zhigang Chen, who is serving for the CLEO: QELS Fundamental Science session of Nonlinear Optics and Novel Phenomena. He mentioned with zeal to me the breakthrough in plasmonic resonance, arbitrary trajectory manipulation of light propagation, using photonic periodic structure to test the idea of super-symmetry, and so on. The depth of the fundamental science he was trying to convey blows me away. Topics like these will always find their places in CLEO, and I always feel this is one of CLEO’s strengths. In fact, the entire QELS program poses a mental stimulus to my brain.  These courses are  so stimulating they are like “ “espresso for the brain!”

The truth is  what I mention here provides  just a small glimpse into all the great content being featured at CLEO. To get a glimpse at the full conference program, visit the CLEO website here!

Iain McKinnie, Lockheed Martin Advanced Technology Center, CLEO: Applications & Technology 2013 Program Chair

This year’s CLEO Conference, sponsored by APS/Division of Laser Science, IEEE Photonics Society and the Optical Society features an expanding Applications & Technology Program focusing on the core areas of Biomed, Energy, Industrial and Government/National Science and Security Standards.  Tom Giallorenzi, OSA’s Science Advisor interviewed Iain Mckinnie, Program Chair, Applications & Technology to delve further into some of this year’s hot topics.

Tom Giallorenzi: Can you say a little bit about technology transitions that this meeting is fostering?

Iain McKinnie:      “………there are many great examples in the Applications and Technology conference that you can see, including quantum cascade lasers.  We have a plenary talk this year which we’re very excited about by Dr. Kumar Patel from Pranalytica who is also a professor at UCLA.  And he’s going to be talking about how those quantum cascade lasers – now room temperature and multi-watt lasers in the midwave and long wave infrared region – are impacting applications from civil aircraft defense via countermeasures, through to trace gas detection for a range of commercial security  and environmental applications.  So that’s one capability that’s transitioning.

There are many more.  In the energy area, we’re looking at increasing transition of broadband nitride semiconductor materials in solar cells and in extending the spectral range of LEDs down into the UV region from the visible region. We’re also seeing increasing transition of ultrafast lasers, which continue to enable advances in manufacturing from the macro to the micro down to the nano scale.  ……. I think that we keep the wow factor in the conference also, and that comes in via big science; with some of the facility class laser systems: electron beams being used to generate extremely short bursts of intense light, and being used to generate extremely broadband, broad spectral access from the UV right out far into the infrared region.  Also, we have a big emphasis this year on the National Ignition Facility and the latest progress that they have achieved in the extreme high field regime.  So, you know, I think as well as things that could have mass market applicability, it’s important that we keep our finger on the pulse of the really impressive landmark advances at the unique and high power end.

Tom Giallorenzi: Can you say a few words about the special symposia?

Iain McKinnie:      One thing we’re very consciously focused on in 2013 at CLEO A&T is to bring in a number of special symposia which we believe represents a pretty broad suite of the application space for lasers that’s emerging.  I mentioned already the symposium related to the national ignition facility.  We have a number of others.  One that we’re excited about at the extreme other end of the scale is a lab on a chip symposium this year where we’re really taking advantage of advances not only in laser and LED sources, but also in microfluidics and nanotechnology and a whole lot of related applications to really take the pulse of that field and get a sense for how lab on a chip is advancing.

Beyond that, we also have a special symposium that’s looking at how the advances in sources are impacting biomedical applications more broadly.  That’s looking at advances in, for example, multi-modal imaging –  and looking at how relatively new sources like super continuum sources are being transitioned over into the application space.  And that’s a good example where there’s a need for those sources to be quieter and so that then flows back to the laser developers to really work on tailoring those sources for those kinds of applications.  I see biomedicine really being one of our significant growth areas in applications in technology in the coming years.
