Abstract: 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.
