光机械谐振腔的辐射压力诱导加热和冷却

Simultaneous radiation pressure induced heating and cooling of an opto-mechanical resonator

Siddharth Tallur, Sunil A. Bhave

摘要:

微机械谐振器的光学和机械模式之间的腔光-力学使能的辐射-压力耦合引起动态反作用,使得能够放大和冷却机械运动。由于大的机械振荡和放大的必要饱和的组合,光机械谐振器的本底噪声增加,使其在转换小信号时无效,从而冷却系统的另一个机械谐振。在这里,我们展示了一个机械谐振放大的微机械环形谐振器,同时冷却另一个机械谐振,利用两个紧密间隔的光学回音壁模式腔谐振。

英文摘要:

Cavity opto-mechanics enabled radiation-pressure coupling between optical and mechanical modes of a micro-mechanical resonator gives rise to dynamical backaction, enabling amplification and cooling of mechanical motion. Due to a combination of large mechanical oscillations and necessary saturation of amplification, the noise floor of the opto-mechanical resonator increases, rendering it ineffective at transducing small signals, and thereby cooling another mechanical resonance of the system. Here we show amplification of one mechanical resonance in a micro-mechanical ring resonator while simultaneously cooling another mechanical resonance by exploiting two closely spaced optical whispering gallery mode cavity resonances.
