成立了(AB)N型一维光子晶体布局多通道可调谐滤波器模子, 个中A层是砷化镓(GaAs)原料, B层是由掺铝的氧化锌层和氧化锌层(AZO/ZnO)瓜代分列组成的具有人工周期布局的各项异性子料。按照电磁波的传输矩阵理论, 推导了光子晶体的透射率公式。数值模仿表白: 此布局光子晶体透射中间波长是1.55 ?滋m, 对应于光子通带; 透射峰的数目由光子晶体的周期N抉择; B层中添补因子h从2/3增进到11/12, 峰值波长蓝移且移动范畴高出200 nm; A和B层厚度增进, 透射峰中间波长产生红移; 而入射角度的增进将使透射峰中间波长蓝移; 在各参数的调控范畴内, 光子晶体均保持较高的透射率稳固。这些征象为光通讯波段多通道可调谐高机能滤波器的计划提供了理论参考。

Abstract

A filter model with one-dimensional photonic crystal structure (AB)N was proposed. Layer A was gallium arsenide (GaAs) material and layer B was an artificial periodic structure material. B was anisotropic and made of aluminum-doped zinc oxide and zinc oxide (AZO/ZnO) alternately. Based on the theory of electromagnetic wave transmission matrix, the transmission rate of photonic crystal was derived. The numerical simulation shows that the center wavelength of the transmission is 1.55 ?滋m and corresponds to the photon pass band. The number of transmission peaks was determined by the period N of the photonic crystal. Increasing the filling factor h of the B layer from 2/3 to 11/12, the transmission peak wavelength was blue shifted and the moving range exceeds 200 nm. Increasing the thickness of the A and B layers, the peak wavelength was red shifted. When the incidence angle increases, the peak wavelength was blue shifted. The photon crystal will maintain a high transmittance within the control range of each parameter. These phenomena provide a theoretical reference for the design of multi-channel tunable high performance filter for optical communication.
