IEEE Student Chapter Seminar: “NanoSilicon NanoPhotonics” - L. Pavesi

CREOL 266

Abstract:

Silicon Photonics is no more an emerging research topica but is an actual technology with commercial products already available on the market. Quantum confinement of carriers or spatial localization of photonics allow to dramatically enhance and widen the scope and potential of silicon photonics.

After a review of silicon photonics where the state of the art is presented, the optical properties of silicon reduced to nanometric dimensions are introduced. The use of nano-Si in silicon photonics (waveguides, modulators, switches, sources and detectors) is reviewed and discussed. Recent advances of nano-Si devices such as bio-imagers, optical resonators (linear, rings, and disks) are treated. The development of high efficiency light emitting diodes for interchip bidirectional optical interconnects is presented as well as the recent progresses to exploit nano-Si for solar cells. In addition, non-linear optical effects which enable fast all-optical switches are described. On the other hand, confinement of photons to small microresonators allows tuning the photon properties. Here also novel effects are found. Ultra high bandwidth robust optical switches for UDWDM, active suspended microdisk bistable devices, nonlinear optical generations are only few applications where nanophotonics can be appreciated.

Biography:

Lorenzo Pavesi is Professor of Experimental Physics at the University of Trento (Italy). Born the 21st of November 1961, he received his PhD in Physics in 1990 at the Ecole Polytechnique Federale of Lausanne (Switzerland). In 1990 he became Assistant Professor, an Associate Professor in 1999 and Full Professor in 2002 at the University of Trento. He leads the Nanoscience Laboratory, teaches several classes at the Science Faculty of the University of Trento. He founded the research activity in semiconductor optoelectronics at the University of Trento and started several laboratories of photonics, growth and advanced treatment of materials. He is the president and founder of the IEEE italian chapter on Nanotechnology. He has directed more than 20 PhD students and more than 20 Master thesis students. His research activity concerned the optical properties of semiconductors. During the last years, he concentrated on Silicon based photonics where he looks for the convergence between photonics and electronics by using silicon nanostructures or photon confinement.

Colloquium: “Searching the Secrets of Nature using Photonics Physics” – Robert R. Alfano

PS 161

Abstract:

The talk will describe the salient properties of light and discuss breaking some of the commonly accepted rules and processes in nature. The following will be discussed: coherence of excitons in primary photon capture and energy transport processes in plant photosynthesis; stitching tissues together using hot vibrations excited by ultrafast laser pulses; breaking De Beers absorption law for deeper penetration of light in water due to ultrafast laser pulse being faster than the depopulation response times; twisting non planar light beam selection rules revealing new transitions in materials; and optical memory in scattering medium.

Biography:

Robert R. Alfano, Distinguished Professor of Science and Engineering at The City College of the City University of New York, is a pioneer in the application of light and photonics technology to the study of biological, biomedical and condensed matter systems and a leader in inventing and using novel light sources as well as developing ultrafast laser spectroscopic techniques. His contributions to the field of photonics over the past 30 years of his professional career are documented in over 700 research articles, 108 patents, several edited volumes and conference proceedings, and well as over 10,000 citations. His research achievements include pioneering contributions in discovering new tunable Cr3+/Cr4+ lasers, developing laser spectroscopic and optical biomedical imaging techniques for noninvasive, pain-free detection and diagnosis of diseases. He has received his Ph.D. in physics from New York University. Received OSA Charles Hard Townes Award in 2008 for supercontinuum discovery and tunable laser development.
