November 17, 2010 Stevens Nanotechnology Seminar Series: Controlling Light in Photonic Structures
The Nanotechnology Graduate Program at Stevens Institute of Technology continues its Seminar Series with “Controlling light in photonic structures,” a presentation by Dr. Chee Wei Wong. Dr. Wong is an Associate Professor in the Center for Integrated Science and Engineering, Solid-State Science and Engineering, and Mechanical Engineering at Columbia University. The seminar will be held Wednesday, November 17 at 10:00 a.m. in Babbio Center Room 122.
In his lecture, Dr. Wong examines the control of photons in engineered photonic crystal nanostructures. First, he describes the strong control of dispersion and localization in photonic crystal structures, leading to the observations of negative refraction, zero-index superlattice band gaps, and ultrahigh-Q subwavelength nanocavities. Coherent interactions lead to his observations of an optical analog to electromagnetically-induced-transparency, and laser cooling in chipscale cavity optomechanics. Second, he reports on studies in nonlinear optics through the tight field confinement and long photon lifetimes in photonic crystal structures. Examples include slow-light enhanced four-wave mixing, soliton dynamics and femtosecond pulse compression (together with Thales), Raman scattering, and optical bistability at the femtojoule level. Third, he describes his efforts on quantum optics in nanostructures. Examples include controlling spontaneous emission through cavity quantum electrodynamics for efficient on demand single photon sources, single quantum dot exciton-photon coupling, and theoretical proposals to realize scalable quantum phase gates for quantum information sciences.
