摘要:

我们已经观察到的非线性转导的热机械运动的纳米机械谐振器检测时,通过边带未解决的光机械腔的激光传输。非线性检测机制是相当感兴趣的特殊情况下,允许量子非爆破测量的机械谐振器的能量。我们调查的光学机械检测装置中的非线性的起源,并推导出一个理论框架的非线性信号转导,和光学弹簧效应,从两个非线性光学传递函数和二阶光学机械耦合。通过测量的线性和非线性信号转导的依赖性-以及机械频移-从光学共振激光失谐,我们提供的线性和二次光机械耦合的贡献估计。

英文摘要:

We have observed nonlinear transduction of the thermomechanical motion of a nanomechanical resonator when detected as laser transmission through a sideband unresolved optomechanical cavity. Nonlinear detection mechanisms are of considerable interest as special cases allow for quantum nondemolition measurements of the mechanical resonator's energy. We investigate the origin of the nonlinearity in the optomechanical detection apparatus and derive a theoretical framework for the nonlinear signal transduction, and the optical spring effect, from both nonlinearities in the optical transfer function and second order optomechanical coupling. By measuring the dependence of the linear and nonlinear signal transduction -- as well as the mechanical frequency shift -- on laser detuning from optical resonance, we provide estimates of the contributions from the linear and quadratic optomechanical couplings.
