摘要:

我们回顾和研究量子和经典波动的作用,在最近的腔光学机械实验,现在已经达到了量子制度(机械声子占有率< 1),使用解决边带激光冷却。特别是,激光噪声加热的机械谐振器和光学转换的机械光谱的形式,修改量子和经典的激光噪声挤压,在各种测量条件下导出。利用这一理论,我们分析了我们最近的基态激光冷却和动态边带不对称实验与纳米光机械晶体谐振器。

英文摘要:

We review and study the roles of quantum and classical fluctuations in recent cavity-optomechanical experiments which have now reached the quantum regime (mechanical phonon occupancy < 1) using resolved sideband laser cooling. In particular, both the laser noise heating of the mechanical resonator and the form of the optically transduced mechanical spectra, modified by quantum and classical laser noise squashing, are derived under various measurement conditions. Using this theory, we analyze our recent ground-state laser cooling and motional sideband asymmetry experiments with nanoscale optomechanical crystal resonators.
