We present an integrated optomechanical and electromechanical nanocavity, in which a common mechanical degree of freedom is coupled to an ultrahigh-Q photonic crystal defect cavity and an electrical circuit. The system allows for wide-range, fast electrical tuning of the optical nanocavity resonances, and for electrical control of optical radiation pressure back-action effects such as mechanical amplification (phonon lasing), cooling, and stiffening. These sort of integrated devices offer a new means to efficiently interconvert weak microwave and optical signals, and are expected to pave the way for a new class of micro-sensors utilizing optomechanical back-action for thermal noise reduction and low-noise optical read-out.
我们展示了一种集成的光机械和机电纳米腔，其中一个共同的机械自由度与一个超高Q值的光子晶体缺陷腔和一个电路相耦合。该系统允许对光学纳米腔共振进行宽范围、快速的电学调谐，并能对诸如机械放大（声子激光）、冷却和硬化等光学辐射压力反作用效应进行电学控制。这类集成器件提供了一种有效互转换微弱微波和光信号的新方法，有望为利用光机械反作用降低热噪声和实现低噪声光学读出的新型微传感器铺平道路。
