论文摘要
缓慢而快速的光是量子光学中的重要且引人入胜的现象。在这里，我们从理论上基于理想的光机电诱导的透明度（省略）来研究如何在被动激活的光机电系统中实现超速和超快光。在理想省略的条件下，将出现一个异常（倒置）透明度窗口，并伴随着非常陡峭的分散体，从而在透明窗口中可以轻松地通过调节两个空腔的耗散速率，即使使用通常的机械线路（例如Hz lineWidth），可以轻松实现Ultraslow Light。特别是，随着被动腔的衰减速率趋向于活跃腔的增益速率，因此可以实现理想的停止光。同样，通过调整系统中的耦合强度和衰减速率，可以在透明窗口中实现超快光。
Slow and fast light is an important and fascinating phenomenon in quantum optics. Here, we theoretically study how to achieve the ultraslow and ultrafast light in a passive-active optomechanical system, based on the ideal optomechanically induced transparency (OMIT). Under the conditions of the ideal OMIT, an abnormal (inverted) transparency window will emerge accompanied with a very steep dispersion, resulting that the ultraslow light can be easily achieved at the transparency window by adjusting the dissipation rates of the two cavities, even with usual mechanical linewidth (such as Hz linewidth). Particularly, as the decay rate of the passive cavity tends to the gain rate of the active cavity, the ideal stopped light can be achieved. Similarly, the ultrafast light can be achieved at transparency window by tuning the coupling strength and the decay rates in the system.
