Photonics confab presents trends, research results

MANHASSET, NY -- More than 550 technical presentations by the world’s leading scientists and engineers in the areas of lasers, optoelectronics, optical fiber networks and associated lightwave technologies will gather for the IEEE Photonics Conference 2011 October 9-13 at the Crystal Gateway Marriott hotel in Arlington, VA.
Some highlights follow:
In his plenary session talk on "What's next in solid state lighting: speculations on the future ecosystem" Makarand Chipalkatti, Sr. Dir. SSL & Emerging Market Initiatives, Osram Sylvania Inc. reports that the lighting industry is in the midst of a significant transformation, with the advent of LEDs (and OLEDs) as new light sources driving this change.
"The change anticipated is somewhat parallel to the transformation of the lighting industry from gas to electric," said Chipalkatti. "The ecosystem resulting from the electrification of lighting consisted of filament materials, electrodes, lamps, luminaires, electrical grid, wiring, and switches."
In his presentation Chipalkatti will review the historical precedents, and the current and future trends in solid state lighting.
Peter Winzer, who heads the Optical Transmission Systems and Networks Research Department at Bell Labs, Alcatel-Lucent, will take a look at wavelength-division multiplexing systems in the second plenary talk.
Today WDM systems can carry close to 10 Tbit/s over a single fiber with research experiments approaching the 100-Tbit/s mark. Recent fundamental studies have pointed at the Shannon limits of (nonlinear) optical fiber transmission, and concluded that current experimental results have reached those limits to within a factor of 2 to 3. In order to further scale network capacities, "space" is the only known dimension yet unexploited.
Space-division multiplexing (SDM) may use parallel strands of single-mode fiber, uncoupled or coupled cores of multi-core fiber, or individual modes of multi-mode waveguides, together with multiple-input multiple-output (MIMO) digital signal processing to address modal crosstalk. Winzer will review the current state of WDM and address some of the key challenges that SDM research will have to address over the coming decade in order to prevent the looming "capacity crunch".
The third plenary by Andrea C. Ferrari head of the Nanomaterials and Spectroscopy group of the Electrical Engineering Division, Engineering Department, University of Cambridge, Cambridge, UK, will look at the richness of optical and electronic properties of graphene: "We believe its true potential to be in photonics and optoelectronics. The rise of graphene in photonics and optoelectronics is shown by several recent results, ranging from solar cells and light emitting devices, to touch screens, photodetectors and ultra-fast lasers."
Meanwhile, Mitsubishi researchers will describe in an invited paper how they used four high-speed (25-Gb/s) lasers in a clever arrangement to achieve 100 Gb/s data transmission rates over Ethernet. (Paper #TuD1, “High-Speed Modulation Lasers for 100 GbE,” A. Sugitatsu et al, Mitsubishi Electric.)
McGill University researchers will detail how they achieved a record 57-percent internal quantum efficiency (electricity-to-light conversion efficiency) over the entire range of visible wavelengths with InGaN/GaN dot-in-a-wire light-emitting diodes (LEDs). (Paper #MH2, “Study On The Quantum Efficiency Enhancement In InGaN/GaN Dot-In-A-Wire Light-Emitting Diodes Grown By Molecular Beam Epitaxy,” H. Nguyen et al, McGill University)
A research team led by Colorado State University will describe the first results obtained with a single-shot, time-resolved, high-resolution Fourier extreme ultraviolet (EUV) holographic imaging system that is able to generate holographic images of objects less than 100-nanometers in size and 1-nanosecond apart. Such a device may lead to an enhanced ability to view objects that are part of dense light-scattering environments, such as tumors within organ tissue. (Paper #ThU4, “Toward Table-Top Time-Resolved Extreme Ultraviolet Fourier Holography, “E. Malm et al, Colorado State University/Military University of Technology (Poland))
University of Maryland researchers will detail a non-destructive imaging technology they have developed to enable better three-dimensional viewing of fluorescent-labeled stem cells within a tissue scaffold over a several-millimeter field of view. (Paper #ThH4, “Three-Dimensional Imaging of Stem Cell Distribution Within Tissue Engineering Scaffolds Using Angled Fluorescent Laminar Optical Tomography (aFLOT),” C-W. Chen et al, University of Maryland)
Lessons in being a photonics entrepreneur is an evening session at the conference and will feature successful photonics entrepreneurs who will present their personal perspectives and insights on successfully commercializing photonics technology. The presenters are: Alexei Glebov,CEO and President, OptiGrate Corp.; David F. Welch, founder, Executive VP, Chief Strategy Officer, Infinera Corp.; Chris Koeppen, Executive Director & General Manager, Aegis Lightwave, Inc.; and Steve Yao of General Photonics Corp.
