Piezo-optomechanical Actuation of Nanobeam Resonators for Microwave-to-Optical Transduction

We demonstrate three methods for microwave actuation of GaAs nanobeam piezo-optomechanical resonators, based on interdigitated transducers, piezoelectric resonators, and micro-antenna structures. Potential applications of these devices range from bi-directional microwave-to-optical conversion to optomechanical thermometry.
