Based on the unique optomechanical coupling between optical and mechanical modes, the cavity optomechanical system has exhibited profound physical meanings and excellent application prospects in the fields of quantum effects and optical nonlinearity. Supported by the micro-nano technology, this system is expected to be designed as a sensing device for detecting micro-physical quantities, due to its excellent characteristics including easy integration, ultralow heat loss, sensitive perceptions for external perturbations and strong nonlinear responses. In this project, we will study the effective theory and exact calculating program to describe the interaction between light and hybrid optomechanical systems. We will systematically investigate the absorption-dispersion properties of linear transmission spectra, nonlinear susceptibility, nonlinear sideband spectra and corresponding quantum coherent control in the hybrid optomechanical systems. According to the above theoretical study, we will also reveal the correlation between the physical properties of the mechanical oscillator and nonlinear sideband spectra, then research the influence of the mechanical oscillator treated as a sensing element on the nonlinear sideband spectra. After seeking the optimized hybrid optomechanical systems, the applications of sensing micro-physical quantities will be designed. The research of this project will be beneficial for understanding and developing the optimization strategies of optical nonlinearity in the cavity optomechanical systems, and promoting the research and application of optical micro-nano quanutm devices.
