Abstract

We impart a theoretical method to enhance optomechanically induced transparency (OMIT) and slow/fast light in a standard optomechanical system composed of a fixed mirror and a moving end mirror. The system is driven by a strong pump field and probed by a weak probe field, respectively. We consider the mass of the mechanical resonator is position-dependent which generates a nonlinear effect in the system. In this paper, we show that the nonlinear parameter α of the position-dependent mass shifts the system from Stokes to the anti-Stokes regime, as a result, OMIT of the transmission field enhances. Further, we show the nonlinear parameter α changes the transparency window from symmetric to asymmetric window profile and looks like Fano resonances. Moreover, in the presence of α, we explain the behavior of mirror field coupling on the width of the transparency window as well. In particular, we present the enhancement of slow/fast light corresponds to the positive/negative dispersion of the phase associated with the transmission probe field.

取决于位置的质量光力学中增强的光力学诱导的透明度和慢/快光

摘要

我们给出一种理论方法来增强由固定镜和移动端镜组成的标准光学机械系统中的光学机械感应透明度（OMIT）和慢/快光。该系统分别由强泵浦场驱动和由弱探头场探测。我们认为机械谐振器的质量与位置有关，这会在系统中产生非线性效应。在本文中，我们证明了位置相关质量的非线性参数α使系统从斯托克斯体制转向反斯托克斯体制，结果，传输场的OMIT增强了。此外，我们显示了非线性参数α将透明窗从对称窗轮廓更改为非对称窗轮廓，并且看起来像法诺共振。而且，在α，我们也解释了在透明窗口的宽度上镜场耦合的行为。特别地，我们提出慢/快光的增强对应于与透射探针场相关的相位的正/负色散。
