研究了简并光学参量放大器（OPA）光机系统中的光机诱导透明（OMIT）和慢光。该系统由简并光学放大器、两个带电机械谐振腔和一个固定反射镜组成。腔体与荷电机械谐振器之间的耦合作用用辐射压力项表示。谐振腔与另一个带电机械谐振器之间不存在相互作用，而两个带电机械谐振器之间存在库仑相互作用。在这样的非线性OMS中，我们通过改变库仑耦合强度、驱动OPA的光场的相位、OPA的非线性参数以及泵浦光的功率来考虑OMIT和慢光。我们发现，库仑耦合强度有一个显着的影响，由于机械修饰模式的两个透明度下降之间的间距。此外，通过调节系统的控制参数，可以实现长寿命的慢光（几毫秒的群延迟）和从超光速到亚光速传播的切换。
A study on optomechanically induced transparency (OMIT) and the slow light in an optomechanical system (OMS) with a degenerate optical parametric amplifier (OPA) is conducted. The system consists of the degenerate OPA, two charged mechanical resonators, and a fixed mirror. The coupling interaction between the cavity and a charged mechanical resonator is expressed by the radiation pressure term. There is no interaction between the cavity and the other charged mechanical resonator, while there is Coulomb interaction between the two charged mechanical resonators. In such a nonlinear OMS, we consider OMIT and the slow light by changing the Coulomb coupling strength, the phase of the optical field driving the OPA, the nonlinear parameter of the OPA, and the power of the pump field. We find that the Coulomb coupling strength has a significant impact on the spacing between the two transparency dips due to the mechanical dressed modes. Moreover, one may achieve long-lived slow light (group delay of several milliseconds) and a switching from superluminal to subluminal propagation via adjustment of the controlling parameters of the system.
