摘　　要：光力诱导透明和慢光效应一直是量子光学领域的研究热点。本文探究了玻色-爱因斯坦凝聚体腔中出现完美光力诱导透明的必要条件,并讨论了驱动场频率失谐对完美光力诱导透明谱线的影响。特别地,发现即使在波戈留波夫模的弛豫速率很大的情况下,也可以实现完美的光力诱导透明现象,这正是完美光力诱导透明理论的优点之一。此外,还讨论了在透明窗口处的慢光效应,发现腔的耗散速率和波戈留波夫模的弛豫速率均对慢光效应有显著的影响,特别是在不可分辨边带参数区域,可实现超慢光效应。这些结果可应用于现代光学网络的建设以及量子信息处理过程。Optomechanically induced transparency and slow light effect have always been the hotspots in the field of quantum optics.Here,the necessary conditions for perfect optomechanically induced transparency in Bose-Einstein condensed cavity are investigated,and the influence of frequency detuning of driving field on perfect optomechanically induced transparency is discussed.In particular,it is found that the perfect optomechanically induced transparency phenomenon can still be achieved even when the decay rate of Bogoliubov mode is very large,which is one of the advantages of the perfect optomechanically induced transparency theory.In addition,the slow light effect at the perfect transparent window is discussed,and it is found that both the decay rate of the cavity and the decay rate of the Bogoliubov mode have significant influence on the slow light effect.Especially,ultra-slow light effect can be realized in the unresolved sideband region of system parameters.The results in this work can be applied to the construction of modern optical networks and quantum information processing in the future.
