应用传输矩阵法研究了由电磁感应透明材料构成的一维光子晶体带隙结构。计算结果表明:通过改变控制光的拉比频率可以调控一维光子晶体的禁带宽度。随着拉比频率的增加,EIT原子气体的相对折射率也随着增加。随着拉比频率的逐渐加大,光子晶体的禁带宽度变得越来越窄,但变化变得越来越慢,即增加相同大小的拉比频率其影响越来越小。 The transfer matrix method was used to study the band gap structure of one-dimensional photonic crystals made of electromagnetic induction transparent material. The calculated results show that the band gap of one-dimensional photonic crystal can be controlled by changing the Rabi frequency of the control light. As the Rabi frequency increases, the relative refractive index of the EIT atomic gas also increases. As the Rabi frequency increases, the bandgap of the photonic crystal becomes narrower and narrower, but the change becomes slower and slower. That is, the effect of increasing the Rabi frequency of the same size is getting smaller and smaller.
