Silicon Photonic Crystal Membrane based Optomechanics

In this talk, I will present our results on the optomechanics of silicon photonic crystal based suspended membrane and edge-defect structures. We have studied and modeled the dynamic response of these devices, which has enabled us to design novel acoustic and magnetic sensors with very small footprint area. Using different edge defect 2D PC slab configurations we have studied the opto-mechanical coupling interaction both experimentally and via modelling. In these studies, we have observed interesting optical bistability and frequency combing phenomena.
