By Howard Lee

Today technical and poster sessions are great as usual. Although it takes me some time to wait before getting a free pizza due to the long queue, I then have chance to chat with my previous advisor at Hong Kong on our recent researches. I enjoyed all these networking sessions filled with food and drinks to discuss science and the latest status of all our friends and colleagues.

The highlight of the day is the post-deadline session in the evening starting at 8pm. These post-deadline papers are selected and recognized as the latest important results in the field of optics and photonics. I attended several talks in these three parallel sessions. Here I would like to highlight some talks that I found of particular interest to me.

Optomechanics with Superfluid Helium-4
(Postdeadline: JTh5B.2)
(G. I. Harris et al., University of Queensland)

This is the first talk I found particularly interesting. The presenter from University of Queensland presented their latest results on the study of optomechanics with superfluid helium-4 in an optical microresonator. He explained that superfluid has the advantages for quantum optomechanics because of their zero viscosity, quantized motion, and the potential of strong phonon-phonon interaction. They tried to use a thin film of superfluid helium onto a surface of an optical whispering gallery mode resonator to investigate the optomechanical effect. Using such super-fluid resonator, they observed Brownian motion with resonance frequency of 330kHz at 580mK. They also studied the photothermal induced laser cooling and heating by detuning the laser. In addition, the Duffing nonlinearity appeared with only ~37 intracavity photons in the sideband and ~1000 intracavity photons in the carrier. The presenter claims that the study opens up a promising system to study macroscopic non-classical mechanical states. We look forward to seeing more results and fundamental studies based on these superfluid Helium-4.

Integrated Continuously Tunable Optical Orbital Angular Momentum Generator
(Postdeadline: JTh5A.5)
(Jie Sun et al., MIT)

Researchers from MIT presented the first demonstration of the generation of tunable orbital angular momentum using integrated silicon photonic circuit and electrical control. They experimentally demonstrate the generation of optical vortex beam with well-defined continuously tunable integer and non-integer OAM states. Their works are definitely an important step to develop ultra-compact on-chip OAM generator that would find a lot of applications in optical communication, optical trapping and sensing.

Technology Transfer — Navigating the Landscape of Today’s Changing Marketplace

Successful transition of technology to commercial product requires a lot of paperwork, navigating intellectual property rights, identifying markets and raising the capital necessary to brings products to consumers. The Technology Transfer Program at CLEO: 2015 provided attendees an invaluable resource for learning how to turn their discoveries into marketable products.

Dr. Milton Chang, managing director of Incubic and author of the book Toward Entrepreneurship, delivered the keynote address of this year’s Tech Transfer program, highlighting his work in bringing new technologies to the market place.

Technology Transfer Keynote Speaker Milton ChangDuring his presentation, Dr. Chang detailed how to start and do business with limited capital. He then went on to explain what gets venture capitalists excited about the photonics industry enough to invest. He also encouraged companies to pool resources, stating that alliances can be mutually beneficial. Finally, he issued a call to students to take an interest in business management and actively participate in professional societies.

Following Dr. Chang’s presentation, the Technology Transfer tutorial featured presentations on technology licensing by Roger Werne, deputy director at Industrial Partnering Office, Lawrence Livermore National Laboratory, and Brent Whitlock, a patent attorney with Drinker, Biddle & Reath LLP. The tutorial covered the many paths to a successful technology transfer and gave attendees an opportunity to learn more about the licensing process, business and legal issues, and finding creative solutions that rewards all parties in a deal.


The Future of Photonics Highlighted in CLEO Post-Deadline Papers

Thursday concluded with late-night, post-deadline paper sessions that featured breaking research from around the world. Technologies discussed included: Optomechanics with Superfluid Helium-4, Plasmonic Nano-Focused Four-Wave Mixing and Dual-Comb Spectroscopy with Frequency-Agile Lasers.


Final Day of the CLEO Conference Features Special Symposia on Next Generation of Ultra-Short Pulse Laser Technologies

The first technological breakthrough in femtosecond technology was done back in the 1970′s using mode-locked dye lasers. These systems were the leading ultra-short pulse technology for twenty years. The invention of titanium-doped sapphire lasers (Ti:Sa) has pushed femtosecond technology to the next tier and has dominated this field for more than two decades. The idea and concept of broadband optical parametric amplification has been well known for years but the realized systems suffered from low power, cost-intensive and unreliable pump lasers in the picosecond range.

By Dr. Rick Trebino, Georgia Institute of Technology Ultrafast Optics Group
An excerpt from SC378: Introduction to Ultrafast Optics

When a measurement averages over many different events, it faces an impossible task: Providing one result when no one result can be correct. In ultrafast optics, this issue has been particularly problematic when using the traditional method of measuring for laser pulses, called intensity autocorrelation and introduced in the 1960’s. When autocorrelation was used to measure trains of different, complex pulses, the resulting measured autocorrelation trace vs. delay (Figure 1.) consisted of a narrow spike atop a broad structureless background. Early researchers often mistook the spike, or “coherent artifact,” for the measure of their pulse length, but its width actually only indicates the much shorter, nonrandom (“coherent”) component of the pulse. The correct pulse length is actually almost always much longer and is instead indicated by the temporally much broader background, which also takes into account the much longer, random (“incoherent”) pulse component.

Given that the task is inherently impossible, it’s worth asking what we should expect. The answer is that the technique should yield a pulse with some characteristics of the typical pulse in the train (e.g., its duration), but, more importantly give an indication of the stability, or randomness, of the pulses in the train.

Although autocorrelation actually does yield some of this information, it yields neither the pulse intensity nor its phase even for the simple case of a stable train of identical pulses and so is now generally considered obsolete.

Images of double pulses

Figure 1. Top: A double pulse and its autocorrelation. Bottom: A train of randomly separated double pulses and their multi-shot autocorrelation (averaged over many pulses in the train). The coherent artifact results from the short nonrandom coherent component of the double pulses (specifically, a single pulse), while the broader background results from the overall average pulse length (the combination of both pulses). This trace is typical of autocorrelations of nearly all trains of unstable complex pulses.

 

Visualization of pulse train.

Figure 2. Top: a stable train of short pulses and its measurement by two modern techniques, SPIDER and FROG. Middle and bottom: Two unstable pulse trains of different average complexity and duration and their measurement. SPIDER yields the same very short pulse (coherent artifact) for all three trains. FROG, on the other hand, yields the correct pulse length, and also indicates the presence of instability.

Figure 2 shows one stable and two unstable pulse trains of varying complexity, and simulated multi-shot measurements of them using two modern pulse-measurement techniques, SPIDER and FROG. Red curves indicate the intensity vs. time, blue the phase vs. time, green the spectrum, and purple the spectral phase.

The stable train of short pulses and unstable trains of longer pulses cannot be distinguished by SPIDER, which always yields the short nonrandom component of the pulses. In short, SPIDER only measures the coherent artifact.  As a result, it probably cannot be used to measure pulse lengths.

FROG also does not see the pulse structure, but it does yield the correct durations.  More importantly, in FROG, the measured FROG trace and retrieved FROG trace (that computed from the measured intensity and phase) disagree for the random trains.  This is the key:  such disagreement in FROG is the indication that instability is present.

SPIDER’s failure should not be surprising: it’s been known for over 200 years that interferometric methods (of which SPIDER is one), in general, are not sensitive to random phase variations, responding only with reduced fringe visibility and increased background. Worse, most other modern pulse-measurement techniques are also interferometric and so also measure only the coherent artifact! Because there is no other indicator available for such instability, most pulse-length claims using these modern techniques require re-evaluation.

So how did some of the brightest scientists in the world make the same mistake twice?  Most likely, it was wishful thinking:  many ultrafast scientists like to be able to brag about having extremely short pulses, and interferometric techniques routinely provide them. But as scientists, we owe it to ourselves, the scientific community, and humankind to be better than this.

About Professor Rick Trebino
Professor Trebino is the co-inventor of FROG and the inventor of GRENOUILLE and a host of other clever techniques for measuring ultrashort laser pulses. He has received wide recognition for this work, including an R&D100 award, a Prism award, a Circle of Excellence award, and the SPIE’s Edgerton Prize for developments in ultrafast measurement technology, and he is a Fellow of the OSA, APS, SPIE, and AAAS.

Plenary III Presenter: Miles Padgett

Plenary III — Celebrating the International Year of Light

Innovators in the field of optics and photonics were recognized last night at the CLEO: 2015 International Year of Light Celebration and Awards Ceremony. The event featured awards from the IEEE Photonics Society, Laser Focus World magazine and The Optical Society. In addition, the crowd was treated to keynote speeches by Nobel Prize recipient Dr. Shuji Nakamura, and 2015 European Science of Light Winner, Dr. Miles Padgett.

“The very idea of having an International Year of Light plenary came up during a planning meeting at CLEO: 2009. It came after The Optical Society’s announcement of LaserFest to celebrate the 50th anniversary of the first laser at events throughout 2010, including CLEO,” said Dr. Peter Smowton, CLEO 2015 general chair and director of research, Cardiff University. “This International Year has brought together over 100 stakeholder organizations in 85 countries, including scientific societies and unions, educational institutions, technology platforms, non-profit organizations and private sector partners. IYL 2015 programs will and are promoting improved public and political understanding of the central role of light in the modern world.”

All the nuclear power plants in Japan have stopped operation, but before the March 2011 tsunami, 30% of the total electricity generation had been supplied by nuclear power plants. It is predicted that by 2020, penetration of the LED lighting market in Japan will be more than 70%, by which consumption of electricity can be reduced by 7%. Dr. Shuji Nakamura, University of California Santa Barbara, USA and Nobel Prize recipient in Physics 2014, shared his quest for more energy-efficient lighting sources.

That light travels in straight lines is a statement of the obvious. But within light beams, energy and momentum can twist and twirl, carrying angular momentum that can spin particles, encode information and test quantum mechanics. Dr. Miles Padgett, Kelvin Chair of Natural Philosophy at the University of Glasgow, Scotland, wrapped up the CLEO: 2015 plenary presentations with his captivating presentation entitled “Light’s Twist.”

CLEO: Market Focus

Three Market Focus sessions were held on Wednesday, including a product presentation from the Laser Focus World Innovation Award winners.

“Precision Manufacturing Using Ultrafast Lasers,” moderated by Michael Mielke, program manager, Micro Processing TRUMPF, Inc., USA, explored the trade-offs between using ultrafast lasers versus conventional tools for high volume, commercial product manufacturing.

The session featured short presentations by industry leaders and explored the economic advantages of using ultrafast lasers in a factory setting. Speakers discussed how to identify the right type of laser source and workstation for specific applications and the overall benefits of using ultrafast lasers over conventional ones.

In addition to Mielke, featured speakers during the session included Mathew Rekow, applications engineering manager, Electro Scientific Industries, Inc.; Herman Chui, senior director of product marketing, Spectra-Physics; and Magnus Bengtsson, director of strategic marketing, Coherent.

The last session of the day was an “Optics and Photonics Market Overview,” moderated by Tom Hausken, senior industry advisor, OIDA.

The session provided an overview of the global photonics market as well as some deeper detail on several niche areas including industrial and scientific lasers and instrumentation. Panelists presented recent market data before taking questions from the audience on the future of the optics market.

“The market has recovered from a downturn in 2012, following the larger one in 2009, and 2014 achieved a new record of $480 billion,” stated Hausken. “The $480 billion includes $200 billion in enabled products, $182 billion of display modules, and $97 billion of other components with a forecast for 2015. With a moderate 6% growth, this indicates a continuing recovery and is relatively strong for such a sizable industry.”

In addition to Hausken, panelists included Alexis Mendez, president, MCH Engineering, LLC; Allen Nogee, senior analyst, Laser practice, Strategies Unlimited; and Shonika Vijay, Lighting Analyst, Strategies Unlimited.

I meant to write a blogpost yesterday but because I was up too late talking to some new people I met at the conference, I didn’t. But that is not too bad as we may explore working together on a new problem!

To me the highlight of Tuesday was the Women in Photonics Lunch that had two very high profile speakers: Prof. Michal Lipson of Cornell University and Dr. Hong Liu, principle engineer at Google Technical Infrastructure. These ladies gave very frank and honest insights into their career paths, the challenges they have faced specific to them being female and their advice for women in general.

When Michal said that people at times assume she works for Alex Gaeta, her husband and also a professor at Cornell, but never the other way round, it produced a wave of a laughter and nods of recognition at what so many women face: being talked over at meetings, being mistaken for the secretary etc. The sub-text or unspoken messages that women are given, of their careers being secondary to their male partner’s or colleagues were all realities that many present in the room could empathise with and perhaps you can too as you read it.

Their advice which works for both women and men contained some real nuggets. For example, “don’t put yourself down because the people around you do that to you”. This action of not internalizing the negative messages from those around us sounds very simple but can be very profound. They also advised everyone to set a high personal standard for oneself. Achieving to a high standard then means we feel more confident and feel we belong and deserve the success that we will hopefully achieve!

Here is an abrupt left turn!

I can’t end the post without talking a little bit about the great talk by Ayman Abouraddy from CREOL, Florida, who gave an invited talk Wednesday morning. He discussed in a very simple and engaging manner the challenges with making multimaterial chalcogenide fibers. He then went on to explain how using polymers in the process his group had overcome these challenges to fabricate large index difference, small diameter, robust fibers with low bend loss. It wasn’t that the Science being explained was necessarily completely new to me, but a good review of the field coupled with very accessible explanations of the challenges and their solutions was valuable. A 30 minute talk allowed me to walk away feeling I have a good handle on the latest on the field of mid IR fibers. So time well spent!

Plenary Session II — On the Process of Finding New Things

CLEO: 2015 continues to be a unique forum for photonics researchers and biomedical applications. Plenary II began with a presentation by Dr. Steven Chu, 1997 Nobel Prize winner in Physics and Professor of Physics and Molecular and Cellular Physiology at Stanford University.

“Science is about discovery, the process of finding new things. Our natural curiosity with the world around us drives our need to observe and discover. Recently, new imaging technologies and techniques, utilizing optics and photonics have increased our ability to see and understand biology at a molecular level, specifically how proteins interact in live cells. It was an honor to have Professor Chu here today to hear more about his research. The work Professor Chu and his team are doing with optics will have a major influence in expanding our knowledge of all living things,” said Dr. Yu Chen, CLEO Applications and Technology Co-Chair and University of Maryland professor.

Light-Emitting Diodes have become common in our daily lives, helping to provide light in our homes as well as give a crisp image on TV and smartphones screens. Dr. Hiroshi Amano is a professor at the Graduate School of Engineering at Nagoya University, Japan. In 2014, he was awarded the Nobel Prize in Physics for his work with LED and solid state lighting.

“Since the mid-1980′s, Dr. Hiroshi Amano has researched the growth and device applications for group III semiconductors. In 1985, his development of low-temperature deposited buffer layers laid the foundation for the creation of high-quality group III semiconductor-based LEDs and laser diodes. Dr. Amano’s research continues to be instrumental in the development and adoption of energy efficient LED lighting around the world,” remarked Dr. Eric Mottay, CLEO Applications and Technology Co-Chair and CEO, Amplitude Systèmes.

“It was my great honor to introduce our Nobel Laureates during the first plenary presentation at CLEO: 2015. This was their first appearance together since their Nobel session in Stockholm and Uppsala where they presented their achievements in this order, starting with the principles and culminating with astounding movies and data.”

CLEO 2015 has begun with a bang. I started it with misplacing my suitcase at San Francisco airport and having to drive back from San Jose to San Francisco to retrieve it. Luckily this unlocked bag that had my laptop and other valuables was not stolen. It seems that the same luck is staying with me in my choice of talks. And I’ll get to these in a bit.

First I sat and made the schedule of social events I want to attend. Monday evening has the Chair’s reception, Tuesday has the Women in Photonics lunch, the 50th anniversary celebrations of the Journal of Quantum Electronics, the conference reception (I am out of breath, are you yet?), Wednesday has the exhibit happy hour and then on Thursday is the pizza lunch!!

I make it a point to attend as many informal events as I possibly can. It is a great way to talk to people in a relaxed setting when they aren’t stressed about their talk or working away on a laptop. A beverage in one hand and a smile on their face, everyone is far more approachable even if you don’t know them already.

Having made my list of technical sessions (after the social!) I was armed and ready to go. I decide to focus on the fiber sessions: “Modes in Fiber” and also “Novel Fiber Materials”.

In the “Modes in Fiber” session the talks covered large mode area fiber designs, as well as fabrication, and went on to some very interesting new ideas on quantum walks in multi core fibers. Large mode area fibers, as a member of the audience pointed out is not a new born field and there are several designs out there. So what makes a design worthy of attention? I think one of the authors answered this very well in his presentation, SM2L.2, when Deepak Jain spoke of the three factors that are key:

  • the metric used to decide what effective single moded operation
  • loss of the fundamental mode
  • the effective radius or area at which bend loss becomes large

This discussion particularly interested me because it is this sort of perspective setting that is so important for good research. At times one can get lost in the virtual forest of journal and conference papers each of which announce a slightly (or hugely) better performance. Yet what is the process for determining which design is really best and will perhaps become the industry standard? This is where conferences like CLEO that bring members of the community together can help find the answers or set people on the path!

Undoubtedly the most exciting talk of the session was SM2L.4 by Peter Mosley from Bath. He showed some exciting simulation and experimental results for multicore fibers, whose propagation constant differences were reconstructed by a Markov chain Monte Carlo simulation, a statistical approach. The striking thing was the difference between the classical behavior one might see (when a particle moves through an array with equal probability of moving left or right) and the non-classical behavior they demonstrated for a photon between coupled waveguides. The waveguides if assumed to have identical coupling strength and uniform propagation constants, immediately show the quantum nature of photons and a very different distribution of end states than the classical particle.

So I was quite pleased with myself for having a chosen a good session and I am looking forward to the next one!

Nobel Prize Winner in Physics 2014
Topic: Current and Future of Solid State Lighting

Amano, an International Year of Light special session speaker, will discuss the current problems with LED lighting. He will offer insights on new lighting technologies, which address these problems.

Steven Chu, Stanford University, USA
Nobel Prize Winner in Physics 1997
Topic: Microscopy 2.0

One of the major problems in the detailed molecular understanding of the biology of genomes is that we cannot currently see what a protein does, where it is and how it moves. As a result, most functional conclusions about a protein are necessarily indirect. In recent years, the invention of new imaging technologies is having a profound impact on biological sciences. Chu will discuss how a revolution in optical and electron microscopy will provide the tools that can have a profound impact on biology, biomedicine and bioengineering.

Highlights from the Technical Program

What do ocean exploration, a smartphone microscope, wide-field microscopy and Hogwarts-like cloaking capabilities have in common? They are all covered at CLEO as a part of the nearly 2,000 presentations taking place this week in San Jose. The technical courses kick off today and continue through Friday.

Highlights include:

  • The Random Raman Laser: A New Light Source for the Microcosmos – Texas A&M University researchers will present how a narrow-band strobe light source for speckle-free imaging has the potential to reveal microscopic forms of life.
  • The Trillion-Frame-Per-Second Camera: Researchers from The University of Tokyo have been able to split a single light pulse into a fast barrage of rainbow-colored daughter pulses. This allows them to capture movies of complex, ultrafast physical and biological processes.
  • A Phone with the Ultimate Macro Feature: If you thought scanning one of those strange, square QR codes with your phone was somewhat advanced, hold on to your seat. Researchers at the University of California, Los Angeles (UCLA) have recently developed a device that can turn any smartphone into a DNA-scanning fluorescent microscope.
  • Two New Technologies Bring a Science Laboratory to the Ocean Floor, Transforming Ocean Exploration: A team of researchers from Woods Hole Oceanographic Institution, Harvard University and the Ocean Exploration Trust have explored an undersea volcano in the Caribbean and created a new sensor to gather chemical data with unprecedented capabilities – all the while sharing the experience in real-time with remote colleagues.
  • No Hogwarts Invitation Required: Researchers from the Karlsruhe Institute of Technology (KIT), in Karlsruhe, Germany, have developed a portable invisibility cloak that can be taken into classrooms and used for demonstrations. It can’t hide a human, but it can make small objects disappear from sight without specialized equipment.

How to Access Technical Papers

Option One: Use the Conference App
Full technical registrants can navigate directly to the technical papers right from the CLEO app. Just locate the session or talk in “Event Schedule” and click on the “Download PDF” link that appears in the description. (NOTE: you will need to log in with your registration information.)

Option Two: Online Access
Technical Digest papers and Postdeadline papers are available from OSA Publishing’s Digital Library. The Digest papers are available now; Postdeadline papers will be available on Tuesday, 19 May.

Tutorial presentations and summaries of invited and contributed papers can be downloaded by individual sessions or by daily .zip files. .zip files are available for 60 days after the conference ends.

After selecting the “Get Technical Papers” button at top left, you will be prompted to log in with the email address and password you used for registration.

NOTE: Some technical registrants will have received an email to first log in or create an account with OSA. If you are in this group or experience difficulty seeing the .zip files or downloading the papers, go to this CLEO webpage, enter your registration code and follow the directions online.
