最近，在两种不同的腔光力学装置中，在兆赫兹范围内观察到了光腔输出光的有质动力压缩。正交压缩在较低的频谱频率下变得特别有用，例如，在引力波干涉仪中，尽管它对过量的相位和频率噪声更敏感。在这里，我们展示了一种由于相消干涉而产生的相位和频率噪声消除机制，它可以促进在千赫兹范围内产生有质动力压缩，并且我们在一个由带有微机械镜的法布里 - 珀罗腔构成的光力学系统中通过实验证明了这一点。
Ponderomotive squeezing of the output light of an optical cavity has been recently observed in the megahertz range in two different cavity optomechanical devices. Quadrature squeezing becomes particularly useful at lower spectral frequencies, for example, in gravitational wave interferometers, despite being more sensitive to excess phase and frequency noise. Here we show a phase and frequency-noise cancellation mechanism due to destructive interference which can facilitate the production of ponderomotive squeezing in the kilohertz range and we demonstrate it experimentally in an optomechanical system formed by a Fabry-P´erot cavity with a micromechanical mirror.
