Just like the spectral signature of materials originates from molecular vibrations, photonic devices have many spectral lines originating from their different mechanical modes. Our group has excited these modes using the radiation pressure produced by light circulating within the device (1, 2, 3) which oscillate regeneratively at controllable mechanical eigen-frequencies up to microwave rates. There is no feedback or externally-applied modulation in the experiment and the optical input is continuous. Microwave-rate oscillations build-up from an inherent parametric process. This is therefore both a spectroscopic technique and a micro-mechanical device.

Current research projects on Conventional and 3D MEMS Inertial Sensors (gyroscopes and accelerometers) involve design, modeling, fabrication, characterization, control system and sensing electronics design, and integration of advanced sensor systems.

In this video we demonstrate comparative analysis of FE modeling and Polytec Scanning Vibrometer MSA-500 experimental measurements.
