Through the number calculation and the theories analysis that designs oping one-dimensional photonic crystal,the characteristic of TM wave and TE wave defect mode resulting from incident argle and the characteristic of TM wave defect mode resulting from thickness of defect were gotten.The defect mode of TM wave have been in the incident angle 0～π/2,the defect mode of TE wave have been in 0～0.65rad.

通过对设计出的一维掺杂光子晶体的数值计算和理论分析，得出了TM波和TE波缺陷模随入射角变化的特征以及TM波缺陷模随杂质光学厚度的变化特征为：TM波的缺陷模透射峰在入射角为0-π/2范围内均存在，而TE波的缺陷模透射峰只在入射角为0-0.65 rad范围内存在；在一定波长范围内TM波缺陷模的波长随杂质光学厚度近似呈线性变化。
