Optimal unidirectional amplification induced by optical gain in optomechanical systems
L. N. Song, Qiang Zheng, Xun-Wei Xu +2
We propose a three-mode optomechanical system to realize optical nonreciprocal transmission with unidirectional amplification, where the system consists of two coupled cavities and…

Optomechanically induced nonreciprocity in a three-mode optomechanical system
Xun-Wei Xu, L. N. Song, Qiang Zheng +2
We propose to create optical nonreciprocity in a three-mode optomechanical system comprising one mechanical and two optical modes, where the mechanical mode is coupled with only on…

Directional amplifier in an optomechanical system with optical gain
Cheng Jiang, L. N. Song, Yong Li
Directional amplifiers are crucial nonreciprocal devices in both classical and quantum information processing. Here we propose a scheme for realizing a directional amplifier betwee…
