Abstract : This grant set out to prove that heterogeneous combination of multiple materials greatly improves optomechanical oscillator performance to point of permitting demonstration of actual real world applications, such as the optical receiver that culminated this work. In this endeavor, the grant has been quite successful, as it has yielded HF to VHF optomechanical oscillators with the lowest in-class room temperature phase noise yet demonstrated. In particular, the energy sharing approach (dubbed Q-boosting) combines polysilicon and silicon nitride materials to allow simultaneous high mechanical Qm and higher optical Qo than attainable by polysilicon material alone.
