论文摘要
我们研究了由两个腔模式和一种机械模式组成的环路耦合的光力学系统中的光子阻滞效应。在这里，机械模式通过光机电耦合到两个空腔模式，它们通过光子跳跃相互作用彼此耦合。通过将光子跳跃相互作用作为扰动，我们获得了与零，一个和两个光子相关的子空间中系统特征值和本征态的分析结果。我们通过分析和数值计算两种空腔模式的二阶相关函数，发现光子阻滞效应中光学模式诱导的声子侧面裂片的现象。这项工作不仅提出了一种通过调整光子跳跃相互作用来选择光子阻滞最佳驾驶频率的方法，而且还提供了一种表征使用空腔光子统计的正常模式分裂的手段。
We study the photon-blockade effect in a loop-coupled optomechanical system consisting of two cavity modes and one mechanical mode. Here, the mechanical mode is optomechanically coupled to the two cavity modes, which are coupled with each other via a photon-hopping interaction. By treating the photon-hopping interaction as a perturbation, we obtain the analytical results of the eigenvalues and eigenstates of the system in the subspaces associated with zero, one, and two photons. We find a phenomenon of optical normal-mode-induced phonon-sideband splitting in the photon-blockade effect by analytically and numerically calculating the second-order correlation functions of the two cavity modes. This work not only presents a method to choose optimal driving frequency for photon blockade by tuning the photon-hopping interaction, but also provides a means to characterize the normal-mode splitting with cavity photon statistics.
