摘 要: | 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。

Defect Features of Doped 1D Anisotropic Photonic Crystals |
| |
Abstract: | In order to research the optical properties of multi-doped 1-D anisotropic photonic crystals, the transmissivity of light wave going through the crystals was calculated with the transmission matrix method. Numerical simulations indicate that: after the light going through the structure of photonic crystal, single, double and multiple defect modes appear along with the number variation of doping layers in TE Wave and TM Wave transmission spectra; the number of defect modes in the bandgap increases with the increasing number of doping layers; the position of defect modes moves to the short-wave direction along with the variation of the optical thickness of doping layer, and the defect modes of TE Waver and TM Waver can be completely separated. This research can provide theoretical basis for the design and production of single or double channel filters. |
