shortcoursesetting14Warm greetings from San Jose, CA. CLEO: 2014 has just gotten off to a great start with a number of short courses on a wide range of hot topics including ultrafast optics, nonlinear optics, metamaterials and nanophotonics. I was really excited about this event for so many reasons- all of which I’m not sure can fit in this one post. The main reason, of course, was to get familiar with current, groundbreaking research on my areas of expertise as well as to increase my industry knowledge on the latest advancements of these particular fields.

There are a number of enthusiastic attendees who showed up early morning for the short course, titled as Nanophotonics: Physics and Techniques. This course was conducted by a leading industry and academic expert with a great personality. He is none other than Prof. Axel Scherer from Caltech. It was really one of the most amazing and informative scientific talks I have ever attended.

What did he cover in his lecture? Prof. Scherer started his presentation describing the necessity of the device miniaturization and its current status worldwide. He then presented several types of micro/nano-resonators to realize high­performance lasers. He also explained how the basic concepts of microwave engineering discovered back to 1950s lead him to develop such resonators in optics/photonics areas. One of the greatest parts of his course which I was amazed with is the contribution he has/will made/make in the area of silicon photonics and its integration with the electronic circuits. Not only this, his lecture also covered how indirect bandgap material, e.g. silicon could be turned into direct bandgap and its evidence by showing his latest results on silicon LEDs. Wow! Isn’t that fascinating?

On the same day, the point of another great attraction was the short course on ‘NanoCavity Quantum Electrodynamics (QED) and Applications’ taught by Prof. Jelena Vuckovic from Stanford. In fact, NanoCavity QED is an exciting field of science and technology that aims to better understand the effect of solid-state light-matter interfaces in order to develop a scalable architecture for quantum communication. After having it highlighted and explained the fundamentals of atom-electromagnetic field interaction, Prof. Vuckovic showed some relevant results her group achieved on nanocavity QED by employing InAs/GaAs quantum dots in photonic crystal nanoresonators. This was a pretty interesting talk, indeed.

Looking forward to the main technical program starting today.

CLEO: 2014 runs 8-13 June 2014 at San Jose Convention Center, CA, USA. Registration is available onsite.

The CLEO team sat down with 2014 Chairs (Bill Munro and Roberto Morandotti, General Co-Chair and Program Co-Chair, Fundamental Science; Rene-Jean Essiambre and Craig Arnold, General Co-Chairs Science & Innovations and Eric Mottay, Program Co-Chair, Applications & Technology) for insight on this year’s esteemed Plenary Speakers. The Chairs also talked about why it is beneficial for technical attendees to stop by the CLEO: Expo, featuring over 300 leading companies from around the world.

CLEO Team:  Can you tell us a little about the Plenary Speakers this year?

Bill MunroI’m very excited about our plenary speaker, Gerhard Rempe, he is one of the world’s leading scientists in the field of quantum communication and quantum technologies. So he’s going to give a beautiful overview of this particular subject area with a talk on Quantum Coherent Networks; and this will lead nicely into the various symposiums that follow. Rempe comes from one of the most prestigious institutions in the world, the Max-Planck Institute, known for their fundamental science.  His accomplishments…are numerous.

Rene-Jean Essiambre:  We are very excited to have Professor Larry Coldren from the University of California at Santa Barbara to talk to us about photonic integrated circuits. Coldren is a very distinguished member of the scientific community. He is a member of the National Academy of Engineering and he has done tremendous contributions to the field. He’s going to talk about photonic integrated circuits at the plenary session. He will discuss the advantages of various integrated technologies and what needs to be done to add functionalities and make them more successful. Photonic integrated circuits have started to make significant commercial impact, and it seems to be destined to do more. This plenary talk is a great opportunity to hear from an expert in the field about challenges and future opportunities for photonic integrated circuits.

Chair is being interviewed by CLEO

OSA Senior Science Advisor interviews CLEO General Chair Rene-Jean Essiambre.

Eric Mottay:   The plenary speaker for Applications & Technology is Dave Payne of Southampton University; and, actually he might not remember but Dave Payne was my supervisor in my very first internship in my career in Southampton; and it’s a leading team which delivered pioneering work on fiber lasers.  Dave Payne is a great speaker, so I’m looking forward to this plenary talk (on Fibres and the future).

CLEO Team: We hear a lot about the Technical Program, but why should attendees also make their way over to the EXPO?

Roberto Morandotti:  I think it’s very important to go to the exhibit; and you may be surprised to hear this since my area is fundamental science but, we need to talk to Industry.  …. I’ve seen a trend which is very pronounced in Canada where I work, but also in the USA and the rest of Europe, in which the government would like us to work together …… to try to develop products together.

So, for me, it’s very important to go to the exhibition, not only to see what are the latest products, and what are the latest lasers and  if I can buy devices that can be used for new research, but also to see … how we can really use the technology or the science we are developing, which somehow is a bit abstract.. it is exciting to really create products that can influence the society, it can be used by the general public, and improve everybody’s life.  So because of this reason , it is becoming for me more and more important to attend these kinds of exhibits

Eric Mottay: The exhibition at CLEO is a further step from the path of science to real life applications.  We see the fundamental sessions of CLEO, application of technology basically showing where the industry will be in three to five years; and the exhibition shows where the industry is right now.  And, it’s a very unique way to get in touch with a number of our scientific customers because of their traction that CLEO has with the scientific community, but also with industrial customers looking into new applications, new processes.

Craig Arnold: Another really exciting trend that we’re having at CLEO this year and something that’s been going on for the past few years has been the interaction between the technical program and the trade show and exhibitors.  One of the really exciting things this year is the continuation of the market-focused program, as well as the technology transfer program.  ..This has been an opportunity for people who are working on technologies and working on science to see how that science and technology is transitioned from their research labs into the real world, so to speak.

So we have a number of interesting speakers coming from both universities, research labs, as well as from industry, to talk about their experiences; and that’s part of the larger program where we’re going to have exhibitors, as well as people developing technologies, talking on the trade show floor.  And this has been an exciting program development, not just for our attendees, but also for the companies and exhibitors that present; and it gives them an opportunity to really see what’s going on in the research field, and for the researchers to really see how their technologies are being applied in the real world.

Search the CLEO: 2014 Online Program for exciting talks and more

Now that the CLEO technical program is finalized, it is really convenient to use the “Itinerary Planner (IP)” available on the CLEO website to search for the research talks that you might be interested in.  With IP, you can save all the talks you plan to attend and populate in a day by day format.  It is also very easy to search for old colleagues, friends, college-mates, etc. with IP and see whether they are an author presenting and attending CLEO: 2014 or not.

Since my research expertise is aligned with nanophotonics and plasmonics, I searched the conference program with the keyword “Plasmonics” and “Metamaterials”. I found that there are quite a few talks/posters which are related to that, with a total of 160 talks/posters this year (Plasmonics: 107, metamaterials: 53). Therefore, I expect I will have a really enjoyable and busy schedule at this year’s CLEO.

Photo of colleagues at conference

Colleagues and friends peruse the hard copy Conference Program. Take a peek at the online version before the conference.

My search of the online program/itinerary planner(IP) resulted in finding several topics and talks of interest, as outlined below:

Hyperbolic and Epsilon-Near-Zero Metamaterials

By making artificial materials with nanostructures which are smaller than the wavelength of light (metamaterial), the electromagnetic response of the material can be tailored and unusual optical properties can be observed in these materials. In the last 2-3 years, specific topics of hyperbolic and ENZ metamaterials have, in particular, attracted a lot of attention as light inside ENZ material experiences extremely large phase velocity and/or exhibits high local density of states, which enables unique optical functions such as tunneling of EM waves and enhancement of spontaneous emission. These metamaterials also have properties that make them ideal for nanoscale optical/quantum communication.

I found that there are several talks related to this topic, this year, that are worth attending. Selected talks are listed below:

Photonic Crystal Fiber

On the other hand, photonic crystal fiber (PCF), a special optical fiber with 2D micro-hollow structure running along the fiber, offers a unique platform with long interaction length and engineerable dispersion for studying of optical sciences, such as supercontinuum generation, optical sensing, frequency comb generation, gas-based nonlinear optics studies, optical tweezers, photochemistry, and so on.

Daniel M. Wasserman, S&I 3 Chair, CLEO: 2014

CLEO Team:              Can you review the talks that you got and were there any themes or any outstanding trends that you were able to discern?

Dan Wasserman:  This was another outstanding year for Semiconductor Laser submissions to CLEO. I think the whole committee was impressed not simply with the quantity of submissions, but more importantly the breadth and quality of these submissions.  I think that one of the trends we are seeing in the contributed submissions is a pushing of the accepted state-of-the-art for a wide range of semiconductor lasers, across a broad range of frequencies.

Many of the contributed talks will focus on ‘going big’: record output powers and high efficiency emitters.  We are seeing impressive examples of this at long wavelengths (mid-IR and THz) with Watt-level or greater powers, using a range of very clever approaches.  At shorter wavelengths, we will have exciting work demonstrating high power VCSELs and photonic crystal lasers.  Other talks focus on going small: nano-scale lasers and ultra-fast pulses.  Finally, we are very much looking forward to a number of papers focusing on integration of III-V laser materials with Si electronics and photonic integrated circuits.

Overall, S&I 3 will offer an impressive array of contributed talks, with a breadth and quality that is indicative of the very best in current semiconductor laser research.

CLEO Team:            Can you tell us a little bit about the Invited  & Tutorial Speakers for S&I 3?

Dan Wasserman: We are so honored to have a line-up of truly incredible speakers accept our invitations to present at CLEO: 2014.  Our tutorial, entitled “Dealing with Losses in Plasmonics and Metamaterials”, will be given by Professor Jacob Khurgin, from Johns Hopkins University, and will provide insight into a major challenge facing future nano-scale optoelectronics.  Anyone who has seen Prof. Khurgin present knows that we are in for a provocative and exciting tutorial!  Our invited talks are also quite exciting, and represent a broad cross-section of current cutting-edge semiconductor laser research.  Prof. Yoshi Yamamoto (Stanford/Tokyo) will be presenting exciting new results on electrically-driven exciton-polariton lasers and Dr. Richard Stevenson (Toshiba Research) will show the latest results on his group’s demonstration of quantum teleportation using entangled LEDs.  Prof. Geert Morthier (Ghent) will provide an overview of his group’s work integrating high-performance micro-lasers onto Si substrates for optical interconnect and logic applications, and Prof. Wolgang Stolz (Philipps University) will discuss his work on near-IR VECSELs grown by MOCVD.   Combined, our tutorial and invited speakers will provide an excellent picture of not only the cutting-edge state-of-the-art in semiconductor lasers, but a glimpse into what the future of semiconductor lasers may well look like!

CLEO Team:               Are there any talks, in particular, that you are looking forward to hearing? If so, why?

Dan Wasserman:       I am, of course, looking forward to all of our talks, it is going to be a very exciting conference this year.  That having been said, I am particularly excited to see recent results on high power long wavelength lasers in presentations from the Meyer group at NRL (high power emission from interband cascade lasers), the Botez and Mawst groups at Wisconsin  (leaky wave coupling of quantum cascade lasers for high power emission), and the Strasser and Unterrainer groups at TU Wien (demonstrating ~1Watt of power from THz quantum cascade lasers).  The demonstration of high power superluminescent emitters, from the Gmachl group at Princeton, will be another exciting presentation.  I will also be looking forward to presentations from Prof. Noda’s group (Kyoto) and Prof. Choquette’s group (UIUC) on high power (>1.5W) and coherently coupled photonic crystal lasers, respectively.  We are excited to have Prof Matsuo’s group (NTT) present recent results demonstrating electrically pumped photonic crystal lasers integrated onto Si substrates.  And finally, I am eager to see a pair of presentations from Prof. Keller’s group at ETH on ultrafast VECSELs and MIXSELs, respectively.                      

CLEO Team:               Thank you very much.

The CLEO Conference, sponsored by APS/Division of Laser Science, IEEE Photonics Society and the Optical Society received record breaking submissions in 2014. The Conference takes place in San Jose, CA, USA, 8-13 June 2014. Visit www.cleoconference.org for program and registration information.

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 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.

If you work in Optics and Photonics, more than likely you have heard about the CLEO US conference. I have been working on Optics and Photonics research for almost 10 years, and have heard from everyone in the community that CLEO is a great peer-reviewed conference. However, because of issues in the past with my visa, I have never been to the CLEO-US conference. This is one of the reasons why I’m very excited about attending CLEO-US this year!

I spent several years in Germany as a graduate student in Max Planck Institute for the Science of Light so I have been to CLEO-Europe twice in 2009 and 2011. The conferences were excellent, and I enjoyed almost everything there, including the short courses, tutorial talks, invited talks, poster sessions, welcome reception and the beer. (yes, German beer is definitely good).

Now I am in US working as a postdoc at California Institute of Technology, and have been invited as a scientific blogger for CLEO-US 2014 in San Jose this year. The first thing I looked up on the CLEO: 2014 official website is the short courses. This is the best place for you to learn something fundamental if you are not very familiar with a particular topic. Scanning through the list of the short courses provided, I find that we have very high-quality speakers lined up this year. As my research focuses are nano-photonics and plasmonics, I am particular interested in the courses of:SCoursePostcard

  • Silicon Photonic Devices and Applications from Michal Lipson (Cornell Univ.)
  • Transformational Optics from Ulf Leonhardt (Weizmann Inst. of Science in Israel)
  • Plasmonics from Mark Brongersma (Stanford Univ.)
  • MetaMaterials from Vladimir M. Shalaev (Purdue Univ.)
  • Quantum Cascade Lasers: Science, Technology, Applications and Markets from Federico Capasso (Harvard Univ.)
  • Nano Photonics: Physics and Techniques from Axel Scherer (Caltech)

Prof. Brongersma’s lectures are the only ones I’ve ever attended amongst the above. According to my personal experience, I would recommend you to attend his short course if you are interested in learning something on plasmonics. I have taken his short courses twice in CLEO-Europe. Prof. Brongersma always gives an excellent course from the basic knowledge to new and interesting ideas about plasmonics. Of course, I believe all courses will be excellent and the choice is all up to you depending on your preferred topic and research interest!

Other than the short courses, I suggest you also look up the titles of the tutorial and invited talks now and find out the exciting talks which are related to your field. I also look forward to seeing the full program schedules and at that time we can go through more carefully all the interesting contributed talks in different topics and all the events.

Let me know if you find any particularly interesting talks at CLEO this year.  I wish I could  attend all of them!  Luckily, CLEO is recording a significant portion of the CLEO technical program.  Full conference registrants can purchase on demand viewing of these talks as an option for only $45 when registering online.

By the way, my name is Howard Lee. I look forward to seeing you at CLEO: 2014 to discuss  the science and  research interests in photonics. Don’t forget to arrange for  registration, hotels, visa etc. in advance, as the US visa application may take 1-2 months depending on the country.

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.

How can we open Open Access even further?

It is fair to say that Open Access (OA) publishing has significantly changed research and scholarship. There has been much debate OpenAccessabout OA, but the principle remains the same: allow everyone access to the published research. Its effectiveness in allowing everyone to publish is perhaps less straightforward. Yet, the trend towards OA is like the arrow of time, pointing in one direction only.

What does it hold for the future?

Simply more OA journals? New and competitive business models? The real future of OA may lie outside the debate outlined above. It may well be to enfold many more things in the embrace of Open Access!
