我们研究了光机械系统（OMS）中压缩腔模式和机械模式之间的非线性相互作用，使我们能够选择性地获得辐射-压力耦合或参数放大过程。即使OMS原本处于弱耦合状态，压缩空腔模式也能将相互作用强度提高到单光子强耦合状态。此外，通过引入与压缩腔模的参数放大相匹配的宽带压缩真空环境，可以完全抑制压缩模的噪声。该提案提供了一种使用压缩腔模式控制OMS的替代方法，该方法应该允许单光子量子过程使用当前可用的光力学技术来实现。潜在的应用范围从工程单光子源到非经典声子态。
We investigate the nonlinear interaction between a squeezed cavity mode and a mechanical mode in an optomechanical system (OMS) that allows us to selectively obtain either a radiation-pressure coupling or a parametric-amplification process. The squeezing of the cavity mode can enhance the interaction strength into the single-photon strong-coupling regime, even when the OMS is originally in the weak-coupling regime. Moreover, the noise of the squeezed mode can be suppressed completely by introducing a broadband-squeezed vacuum environment that is phase matched with the parametric amplification that squeezes the cavity mode. This proposal offers an alternative approach to control the OMS using a squeezed cavity mode, which should allow single-photon quantum processes to be implemented with currently available optomechanical technology. Potential applications range from engineering single-photon sources to nonclassical phonon states.
