为了研究多掺杂一维各向异性光子晶体的光学特性,采用传输矩阵法计算了光波通过多掺杂一维各向异性光子晶体的透射率。经数值模拟得到:光通过该结构光子晶体后,TE波和TM波的透射谱中随掺杂层个数的变化出现了单、双及多缺陷模,禁带中缺陷模的个数随掺杂层数的增大而增多,缺陷模的位置随掺杂层光学厚度的变化向短波方向移动,TE波和TM波的缺陷模能完全分开,透射谱的这一特点为设计制作单、双通道滤波器提供了理论依据。 In order to study the optical properties of multi-doped one-dimensional anisotropic photonic crystals, the transmission of light waves through one-dimensional anisotropic photonic crystals with multiple doping was calculated by transfer matrix method. The numerical simulation shows that single, double and multiple defect modes appear in the transmission spectrum of TE wave and TM wave with the number of doped layers when light passes through the photonic crystal. The number of defect modes in the forbidden band varies with the number of doped layers The number of defects increases with the increase of the number of miscellaneous layers. The position of the defect mode shifts to the shortwave direction with the change of the optical thickness of the doping layer. The defect mode of TE wave and TM wave can be completely separated. Channel filter provides a theoretical basis.
