This project aims to demonstrate Radiation Pressure driven Optomechanical Oscillators (RP-OMOs) with low phase noise and low power operation suitable for various applications in optical and RF communications. In particular, chip scale atomic clocks with low power consumption can be realized by replacing its power-hungry quartz-based microwave synthesizer with the proposed RP-OMO structure. The Q-boosted RP-OMO design approach of this work makes it possible to optimize both optical and mechanical design to simultaneously reduce the phase noise and threshold power of these oscillators while providing electromechanical coupling for electrical output and voltage controlled frequency tuning, as needed for the intended CSAC application.
