An opto-electro-mechanical system based on evanescently-coupled optical microbottle and electromechanical resonator

摘要

Evanescent coupling between a silica optical microbottle resonator and a GaAselectromechanical resonator is demonstrated. This coupling provides highoptical sensitivity and efficient piezoelectric controllability of mechanicalmotion. Opto-electro-mechanical feedback control based on optomechanicaldetection and electromechanical control is performed in both heating andcooling regimes at room temperature. This feedback scheme can be extended tothe efficient control of thermal mechanical motion in electromechanicalresonators with arbitrary structures and materials.
