Nonlinear Optics: Past Successes and Future Challenges
CLEO: Science & Innovations
Robert W. Boyd, University of Ottawa, Canada
Dr. Robert W. Boyd has been an internationally recognized leading scientist in nonlinear optics for over 30 years. In 2010, he became Canada Excellence Research Chair in Quantum Nonlinear Optics and Professor of Physics at the University of Ottawa. His research interests include studies of "slow" and "fast" light propagation, quantum imaging techniques, nonlinear optical interactions, studies of the nonlinear optical properties of materials, and the development of photonic devices including photonic biosensors. Professor Boyd holds a PhD in physics from the University of California at Berkeley, and received his bachelor’s degree in physics from the Massachusetts Institute of Technology. Dr. Boyd has written two books, co-edited two anthologies, published over 300 research papers, and been awarded eight patents. He is the 2009 recipient of the Willis E. Lamb Award for Laser Science and Quantum Optics. He is a fellow of the American Physical Society (APS) and of the Optical Society of America (OSA). He has also served as an APS representative and chair of the Joint Council on Quantum Electronics (joint among APS, OSA and IEEE/LEOS). Professor Boyd has served as a member of the Board of Editors of Physical Review Letters and is currently a member of the Board of Reviewing Editors of Science Magazine.
Abstract
The field of nonlinear optics is now fifty years old. We present a brief survey of past successes of this field and then analyze the equally exciting current status and future prospects of this field.
Development of nonpolar and semipolar InGaN/GaN light-emitting diodes (LEDs) and Laser Diodes
CLEO: Applications & Technology
Steven Denbaars, University of California, Santa Barbara, USA
Dr. Steven P. DenBaars is a Professor of Materials and Co-Director of the Solid-State Lighting and Energy Center at the University of California Santa Barbara. In 2005 he was appointed the Mitsubishi Chemical Chair in Solid State Lighting and Displays. From 1988-1991 Prof. DenBaars was a member of the technical staff at Hewlett-Packard's Optoelectroncis Division involved in the growth and fabrication of visible LEDs. Specific research interests include growth of wide-bandgap semiconductors (GaN based), and their application to Blue LEDs and lasers and high power electronic devices. This research has led to the first US university demonstration of a Blue GaN laser diode. He received a NSF Young Investigator award in 1994 and the IEEE Fellow award in 2005. He has authored or Co-authored over 600 technical publications, 250 conference presentations, and holds over 30 patents.
Abstract
LEDs fabricated from gallium nitride have led to the realization of high-efficiency white solid-state lighting; a review of the unique polarization anisotropy in GaN is included for the different crystal orientations. Emphasis on nonpolar LEDs will highlight high-power violet and blue emitters and considers the effects of indium incorporation and substrate miscut. Semipolar GaN materials has enable the development of LEDs in green, and recent achievements of green laser diodes at 520nm.

Time-Reversed Waves and Subwavelength Focusing
CLEO: QELS – Fundamental Science
Mathias Fink, Ecole Supérieure de Physique et de Chimie Industrielles de la Ville de Paris (ESPCI), France
Mathias Fink is professor at the ESPCI ParisTech and the Director of the Institut Langevin. He is a member of the French Academy of Sciences and holder of the Chair of Technological innovation at the Collège de France. In 1973, he took part in the development of the first real-time medical ultrasound echographs, working in cooperation with General Electric and Philips. He then worked on the analogy existing between sound waves, quantum mechanics and optics. More recently, he has turned his attention to the development of new medical imaging techniques and time-reversal signal processing in complex and disordered propagation media. Since 2009, he has been Director of the Institut Langevin, a re-grouping of the laboratories of Waves and Acoustics and the laboratories of Physical Optics of ESPCI ParisTech.
Abstract
According to time-reversal symmetry, a broadband wave can be focused both in time and space regardless of the complexity of a scattering medium. The broadband nature of time-reversed waves distinguishes them from continuous phase-conjugated waves and allows revisiting the origin of diffraction limits, suggesting new ways to obtained subwavelength focusing for broadband signals in media made of coupled subwavelength resonators. A review of this field in ultrasound, microwaves and light will be presented.
Silicon Integrated Nanophotonics: Road from Scientific Explorations to Practical Applications
CLEO: Science & Innovations
Yurii A. Vlasov, IBM TJ Watson Research Center, USA
Dr. Yurii Vlasov is the Manager of Silicon Nanophotonics Department at the IBM TJ Watson Research Center. Prior to IBM, Dr. Vlasov developed semiconductor photonic crystals at the NEC Research Institute in Princeton, and at the Strasbourg IPCMS Institute, France. He also was, for over a decade, a Research Scientist with the Ioffe Institute of Physics and Technology in St. Petersburg, Russia working on optics of semiconductors and photonic crystals. He received his MS from the University of St.Petersburg (1988) and PhD from the Ioffe Institute (1994), both in physics. Dr. Vlasov has published over 100 highly cited journal papers, filed over 30 US patents, and delivered over 150 invited and plenary talks in the area of nanophotonics. He served on numerous organizing committees of conferences on nanophotonics under OSA, IEEE, LEOS, APS, MRS, etc. Dr. Vlasov was elected a Fellow of both the OSA and the APS, as well as a Senior Member of the IEEE. He was awarded several Outstanding Technical Achievement Awards from IBM and was named a scientist of the year by the Scientific American journal. Dr. Vlasov also served for a few years as an adjunct professor at Columbia University's Department of Electrical Engineering.
Abstract
Silicon Nanophotonics enables single-chip integration of electrical circuits with optical devices scaled down to diffraction limit. Ultra-low power silicon interconnects that link racks, modules, and chips together can enable future large-scale datacenters and Exaflops supercomputers.
