摘要
运用光学传输矩阵理论对一维三元光子晶体传输特性进行了数值计算。结果表明,其带隙宽度随结构参数a、b明显的改变;适当调节两个参数,得到了带隙相对宽度(Δω/ω0)为68%的带隙结构,带隙宽度几乎不随入射角的变化而改变,并且随实际操作中带来的随机误差引起的无序度的改变不明显,由此可方便地用于制作全角宽带反射镜等光学器件。
Optical trnasmission characteristics of one dimensional polybasic photonic crystals composed of three kind of dielectric mediums was studied by the optical transmission matrix method.The results indicate the band gap changes with the variation of structure parameter a and b,a wide band gap with relative band width (Δω/ω_0) of 68 % can be get by adjusting a and b,and its width changes lightly with the incident angle,influence of the disorder is small comparing with binary photonic crystals.So it was suggested to make wide band refleceors with the photouic crystal.
