参量放大器腔中光力诱导透明与本征模劈裂性质

研究了在含有光学参量放大器的光力学腔中关于弱探测光的光力诱导透明与本征模劈裂的性质.研究发现,光学参量放大器的驱动场相位和非线性增益值的大小对光力诱导透明窗口宽度和本征模劈裂性质有非常重要的影响,特别是当控制光频率工作在光力学红边带下,通过适当调制相位和非线性增益可以实现比空腔时(没有光学参量放大器时)还狭窄的光力诱导透明窗口,此时伴随着陡峭的色散曲线.这些研究结果有利于在光力耦合系统中实现快慢光、光存储等量子信息处理过程.

Optomechanically induced transparency and normal mode splitting in an optical parametric amplifier cavity

We study the properties of optomechanically induced transparency and normal mode splitting in an optical parametric amplifier (OPA) cavity. We find that the value of phase of the field driving the OPA and the nonlinear gain of the OPA will evidently affect the width of the optomechanically induced transparency window and the property of the normal mode splitting. In particular, when the coupling field works at the mechanical red sideband, narrower transparency window than the case of empty cavity (no OPA) can be realized by adjusting the value of phase of the field driving the OPA and the nonlinear gain of the OPA, accompanied by the steep dispersion curve. These results may be applied to the realization of fast/slow light, and light storage in optomechanical system.
