摘　　要：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。Using the Transfer matrix method to reserch the one-dimensional photonic crystal bandgap structure which is made of electromagnetically induced transparency atomic vapor.The results show that the photonic crystal bandgap can be manipulated by varying the refractive index of electromagnetically induced transparency atomic vapor.The EIT atomic vapor relative refractive index gradually increasing with the Rabi frequency.With the Rabi frequency gradually increasing,the band gap of the photonic crystal becomes more and more narrow,but the change is becoming slower.
