中文摘要： 腔光力系统是通过光辐射压作用将光学元件（光腔）和力学元件（机械振子）耦合形成的混杂系统，它通过混杂的方法把不同物理系统的优点结合在一起，在量子调控、全光通讯及光信息处理方面有着重要的应用价值，因而迅速成为量子光学和非线性光学领域中的一个全新研究方向。目前，大量的理论和实验工作研究了简单腔光力系统中的非线性光学性质，而对较为复杂的腔光力系统中的光学行为缺少系统深入的研究。本项目拟以原子系综-光腔-机械振子三元耦合腔光力系统为研究对象，通过求解海森堡-朗之万方程组的方法，系统地讨论该耦合系统中的非线性光学行为，包括光学双稳行为、电磁诱导吸收效应、快光效应及高阶边带效应等。本项目旨在揭示原子系综-光腔-机械振子三元耦合腔光力系统中的光学现象和特征，实现对该系统中光学行为的有效调控，为该系统在全光通信及光信息处理方面的实际应用奠定理论基础，为研究复杂腔光力系统中的光学特征提供依据。

英文摘要： Cavity optomechanical system is composed of an optical element (optical cavity) and a mechanical one (mechanical resonator) via the radiation pressure of light. It selects all the merits of different physical systems by the hybrid method, has become a new field in quantum optics and nonlinear optics due to its potential applications in quantum control, all optical communication, and optical information processing. Recently, a lot of theoretical and experimental researches on the optical properties have been done in the cavity optomechanical systems with two coupling elements. However, just a few authors have paid attention on the optical phenomena in the complicated cavity optomechanical systems. This project proposes to discuss the nonlinear optical properties systematically in a hybrid cavity optomechanical system with three coupling elements as the atoms, the cavity and the resonator by solving Heisenberg-Langevin equations. The optical bistability, electromagnetically induced absorption phenomenon, fast light effect, and the higher-order sidebands effect will be discussed detailedly in this hybrid system. This project aims at revealing and effectively controlling the optical phenomena and the properties in this hybrid cavity optomechanical system. This project provides the theoretical basis for the possible applications of this hybrid cavity optomechanical system on all optical communication and optical information processing, and also paves the way for researching the optical properties in the complicated cavity optomechnical systems.
