Abstract

The optical bistable characteristics of an optomechanical ring cavity containing a two-level atomic ensemble and Coulomb interaction between a cavity mirror and an external nanoresonator are theoretically investigated. Dynamics of the hybrid systems is actuated by Heisenberg–Langevin equations of motion. We derive the mean photon number equation and study the steady-state solution behavior. The optomechanical ring cavity exhibits the optical bistability by selecting appropriate parameters. In addition, we investigate the effect of parameters on optical bistability. The optical bistability threshold and the width of the optical bistability curve can be controlled by adjusting the vibration frequencies of the movable mirrors, the two-level atomic ensemble coupling strength, Coulomb interaction coupling strength between a cavity mirror and an external nanoresonator and the cavity decay rate.

带有原子团和库仑相互作用的光机械环形腔中的可控光学双稳态性

本文从理论上研究了包含两级原子团的光机械环形腔的光学双稳态特性，以及腔镜与外部纳米震荡器之间的库仑相互作用。混合系统的动力学由海森堡-朗格文运动方程驱动。我们推导出了平均光子数方程，并研究了稳态解行为。通过选择适当的参数，光机械环形腔表现出光学双稳态性。此外，我们还研究了参数对光学双稳态的影响。光学双稳态阈值和光学双稳态曲线的宽度可以通过调节可动反射镜的振动频率、两级原子集合耦合强度、空腔反射镜与外部纳米谐振器之间的库仑相互作用耦合强度以及空腔衰减率来控制。
