摘要/Abstract

摘要： 研究了含有两条特殊路径的环形光力系统的光学传输特性,这两条路径结构相互独立但彼此间存在声子、光子耦合。通过调节两条独立耦合路径间的耦合强度以及有效光机械耦合率等参数，系统展现出了诱导透明现象的可调谐性。在耦合强度较大时会产生对称失谐点透明峰，距离和强度均可由路径耦合强度调控，从而使基于该系统的全光子开关在理论上成为可能。此外，通过对相关参数的调节，能够轻易地改变透射光的群延迟大小，通过多种途径实现快、慢光的可调谐性。在部分条件下，系统展现出对快慢光调制的优良特性，为相关光子器件的制作与量子现象的研究提供了一个好的平台。

Abstract: The optical transmission characteristics in a ring cavity optomechanical system with two special paths are studied. The structures of the two paths are independent of each other, but there are phonon and photon coupling between them. By adjusting the coupling intensity and the effective optomechanical coupling rate of the two independent coupling paths, the system shows the tunability of inducing transparency. When the coupling intensity is large, the transparent peak of symmetric detuning point will be produced. And the distance and intensity of the transparent peak can be regulated by coupling intensity of the two paths, which makes the all-optical switching based on the system feasible in theory. In addition, the group delay of transmitted light can be easily changed by adjusting the relevant parameters, and the tunability of fast and slow light can be realized by many ways. Under some conditions, the system shows the excellent characteristics of fast and slow light modulation, which will provide a good platform for the fabrication of related photonic devices and the research of quantum phenomena.

Key words: quantum optics, cavity optomechanical system, optomechanically induced transparency;slow light, fast light
