摘　　要：研究了以GaAs为背景介质,将一定密度的EIT原子气体充入二维圆柱六边形晶格光子晶体中,通过调控自发射率、无辐射衰变率、控制光的Rabi频率、原子数密度等外参数以及圆的结构参数,使高频区的能带从完全光子带隙向零带隙转变.The authors design a two- dimensional photonic crystal with a hexagon lattice of air cylinders, which are filled with the EIT atomic vapor in the GaAs backgroud material. It shows that the tunable band gap in the high region of normalized frequency could be achieved by choosing the specific parameters such as the spontaneous activity rate, dephasing rate, Rabi frequency of controllable light, atomic number density as well as circle geometric parameters.
