Nanofabulous Seminar: Photonic Crystal based opto-mechanical sensors and device components for photonic integrated circuits
There is increased interest in silicon and silicon nitride based photonic integrated circuits for a variety of applications. In this talk I will present an overview of work at Western Nanophotonics Sensors Engineering (NPSE) lab on developing opto-mechanical sensors and device components for photonic integrated circuits. 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. We have developed opto-mechanical sensors and observed interesting frequency combing phenomena. Recent work in our group has focused on the design of low power opto-mechanical phase shifters using photonic crystal edge defects for communication and photonics circuit applications.
