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.
