BPN651: Low Power, Low Noise Cavity Optomechanical Oscillators

Project ID BPN651

Abstract Cavity optomechanics is a new and rapidly advancing field in which light is used to alter the properties of a mechanical element. Our project specifically aims to enhance mechanical motion by means of optical radiation pressure in a cavity of both high optical and mechanical quality factors. When enough light is built up in such a cavity, the mechanical self-oscillation results in precisely modulated light at the cavity output. Though there may be numerous applications for cavity optomechanics, we seek to use optomechanical oscillators as a replacement for power-hungry microwave oscillators in chip scale atomic clocks. This work focuses on the RF photonic experimentation necessary to characterize and improve microfabricated optomechanical devices for the target application which requires a low phase noise optical carrier oscillator capable of operating at 3GHz.
