摘　　要：利用数值计算研究了级联一维光子晶体的光子带隙特征。首先给出了级联光子晶体的设计简图和结构参数,分别讨论了单个光子晶体、级联两个光子晶体和级联三个光子晶体的带隙特征,重点分析了级联三个光子晶体带隙宽度的变化,然后在级联三个光子晶体的情况下,分别讨论了TE波和TM波随初始入射角变化时所产生的光子带隙变化。Properties of photonic bandgap of cascaded one dimensional photonic crystals are investigated by means of numerical calculation. Firstly, the designed diagram and structure parameters of cascaded photonic crystals are presented. The bandgap characteristics of single, cascaded two- and three photonic crystals are, respectively, discussed, in which the case of cascaded three photonic crystals is analyzed in detail. And then, in the case of cascaded three photonic crystals, the photonic bandgaps induced by both TE wave and TM wave are, respectively, discussed by changing the initial incidence angles.
