光学非互易器件是光学系统中重要的组成部分, 例如光隔离器. 为了提高这类器件的隔离特性, 提出一种双腔双光力系统, 系统以两种大小不同的光力耦合强度分别与两光学腔相耦合. 该系统在红失谐场的驱动下, 通过调控相位差既可以实现光非互易现象, 又能决定光在系统中透过与隔离的方向, 这种性质来源于光力耦合相互作用和光学腔模耦合之间的量子干涉效应. 研究过程中把系统中相关算符用其平均值加各自的相对涨落值来表示, 然后由涨落值利用输入-输出关系得到系统的传输振幅, 进而得到系统隔离率. 讨论了系统隔离率随光力耦合强度变化的分布情况, 发现两个力学振子的共同作用能使系统有更高的容错率. 该系统通过选用一个品质因数更高的力学振子, 能够实现两种特定频率光的较大隔离率, 并且同时能够保证共振频率信号的反向传输 .
Optical non-reciprocal devices such as the isolators are quite important components in optical systems. To realize the non-reciprocal transmission of the light, the Lorenz reciprocity theorem must be broken first and the main method is that Faraday magnetic rotation effect is used to change the polarization state of the signal through magneto-optical materials. However, this method is difficult to achieve on-chip integration. So using optomechanical system is presented to overcome the difficulty. In order to improve the isolation characteristics of the device, a double-cavity double-optomechanical system, which is coupled to two optical modes by two mechanical oscillators with two different optomechanical coupling strengths, is proposed. Driven by the red detuning field in such a system, the non-reciprocal phenomenon can be realized by regulating the phase difference, and the direction of light transmission and isolation can be determined as well. This property is determined by the quantum interference effect between the optomechanical coupling strengths and the couplings of the optical cavity modes. The method is that the relative operators are represented by their average value plus their relative fluctuations, and then according to the input-output relationship the transmission amplitude and the isolation rate are obtained. We mainly discuss the distribution of the isolation rate as a function of the optomechanical coupling strength. The results are that the combined action of two mechanical modes can make the system have higher fault tolerance rate. The other mechanical mode can make the system achieve a large isolation rate at two specific frequencies and the reverse transmission in the resonant frequency signals at the same time. -
