Title: Manipulating Motion with Light at the Micro-/Nano-scopic scale: Cavity Optomechanics and Its Application

Speaker :Qiang Lin ,University of Rochester

Location:  Room 111, Physics Building

Time: 15:00-16:00, Wed, June 25, 2014

Abstract:

In this talk, I will discuss our recent progress in exploring quantum nonlinear optical and optomechanical phenomena in micro-/nano-photonic devices, with a focus on cavity nano-optomechanics and its application. Optical control of mechanical motion in resonant photonic structures currently attracts significant interest due to its intriguing capability of manipulating photon-phonon interaction.  After a brief introduction to the basic principles of the design and fabrication of optomechanical devices in mainstream semiconductor materials, I will give an overview of the current state of research frontiers on nano-optomechanics, then I will move on to discuss our recent effort on developing different micro-/nano-optomechanical structures on new platforms, on exploring new optomechanical phenomena and physics, and on applying cavity-optomechanical effects for applications in metrology, sensing, and photonic signal processing.
