我们提出了一个详细的理论分析的弱驱动，多模光学机械系统，其中两个光学模式强烈和近共振耦合到一个单一的机械模式通过三波混频相互作用。我们计算了两个光场的一次和两次强度相关性，并将它们与原子-腔系统中的类似相关性进行了比较。当光机耦合g超过腔衰减率kappa时，就会出现非经典光子相关性，我们讨论单光子和双光子共振以及量子干涉的特征。我们还发现了一个长寿命的相关性，衰减缓慢的机械衰减率γ，反映了一个单一的声子状态检测后的光子预示着准备。我们的研究结果提供了深入了解多模光力学的量子机制，与光子和声子的量子信息处理的潜在应用。DOI：10.1103/PhysRevA.87.013839
We present a detailed theoretical analysis of a weakly driven, multimode optomechanical system, in which two optical modes are strongly and near-resonantly coupled to a single mechanical mode via a three-wave mixing interaction. We calculate one- and two-time intensity correlations of the two optical fields and compare them to analogous correlations in atom-cavity systems. Nonclassical photon correlations arise when the optomechanical coupling g exceeds the cavity decay rate kappa, and we discuss signatures of one-and two-photon resonances as well as quantum interference. We also find a long-lived correlation that decays slowly with the mechanical decay rate gamma, reflecting the heralded preparation of a single-phonon state after detection of a photon. Our results provide insight into the quantum regime of multimode optomechanics, with potential applications for quantum information processing with photons and phonons. DOI: 10.1103/PhysRevA.87.013839
