摘要:

基于综合规范场的光的光学隔离、非互易相位传输和拓扑相位是近年来的研究热点。腔光学机械系统,涉及两个光学模式耦合到一个共同的机械模式形成一个理想的平台,以实现这些效果,提供了各种最近的演示光学机械诱导的非互易光传输的基础。在这里,我们建立了一个统一的理论框架来分析光学非互易性和时间反演对称性的破坏多模光机系统。我们强调了两种实现隔离的一般情况,依赖于光学或机械损耗。根据损耗机制,我们的理论定义了这些系统中最佳隔离和可用操作带宽的最终要求。我们还分析了边带分辨率对光机械隔离器性能的影响,强调了即使在未解决的边带制度中也可以保持非互易性的事实。我们的研究结果提供了广泛的一类参数调制非互易器件的一般见解,铺平了道路,为低噪声集成纳米光子学的最佳非互易系统。

英文摘要:

Optical isolation, non-reciprocal phase transmission and topological phases for light based on synthetic gauge fields have been raising significant interest in the recent literature. Cavity-optomechanical systems that involve two optical modes coupled to a common mechanical mode form an ideal platform to realize these effects, providing the basis for various recent demonstrations of optomechanically induced non-reciprocal light transmission. Here, we establish a unifying theoretical framework to analyze optical non-reciprocity and breaking of time-reversal symmetry in multimode optomechanical systems. We highlight two general scenarios to achieve isolation, relying on either optical or mechanical losses. Depending on the loss mechanism, our theory defines the ultimate requirements for optimal isolation and the available operational bandwidth in these systems. We also analyze the effect of sideband resolution on the performance of optomechanical isolators, highlighting the fact that non-reciprocity can be preserved even in the unresolved sideband regime. Our results provide general insights into a broad class of parametrically modulated non-reciprocal devices, paving the way towards optimal non-reciprocal systems for low-noise integrated nanophotonics.
