摘要
为了研究1维光子晶体中光的全反射贯穿效应及其偏振滤波特性,利用传输矩阵法计算了TE波和TM波在大于全反射角入射1维光子晶体的透射率,发现在透射波中出现了全反射贯穿效应。研究了TE波和TM波的全反射贯穿效应随介质光学厚度和周期数的变化特征,表明:全反射贯穿峰的频率随介质光学厚度的增加而减少,全反射贯穿峰数与周期数相等。且全反射贯穿效应具有优良的偏振滤波特性,利用这些特性可以设计出结构简单、控制方便的1维光子晶体的偏振滤波器。
To study the total reflection through effect and filtering properties of 1D photonic crystal,the transition matrix method is adopted to calculate the transmissivity of TE wave and TM wave propagating through 1D photonic crystal with incident angle greater than full reflection angle.Variation of the through effect with the medium optical thickness and cycle number of 1D photonic crystal is obtained.The frequency of total reflection peaks decreases with the increase of the medium optical thickness,and the numbers of total reflection peaks and crystal cycles are equal.The through effect has excellent polarization filtering properties,with which simple-structured and easy-to-control polarization filters can be designed.
