Manipulation of light via high sensitivity charge sensors and a parametric amplifier in a hybrid cavity optomechanical system

In this study, we theoretically investigate the optical response characteristics of an output probe field in a hybrid double-cavity optomechanical system, which consists of a gain cavity, a charged object, along with a passive cavity that is made up of an optical parametric amplifier (OPA). There is a change from bistability to tristability when OPA and the charged parts are included. The combined impacts of OPA, gain-loss parameters, and coupling strength may be used to manipulate optical transmission rates as well as optical second-order sideband (OSS) efficiency. We further demonstrate how boosting the number of charges may significantly improve OSS efficiency. Specifically, we show that by modifying system settings, one may transition from slow to fast light or vice versa. Our findings indicate a suitable platform for improving or steering optomechanically generated transparency devices, with potential applications in optical communications, precise measurement, storage, and sensitive technology.
