摘要

文章采用有限元法分析了基于环形腔的光子晶体T型滤波器的滤波性能

比较了整体介质柱及内柱折射率对滤波器输出端口归一化透射率曲线的影响。在此基础上设计了一种窄带光子晶体环形腔的滤波器模型

数值模拟结果显示微环腔内部介质柱折射率与窄带滤波器下路波导输出的中心波长之间存在着近似线性的依赖关系

这为光子晶体滤波器的设计与制作提供了理论参考。

Abstract

In this paper

the ring resonator-based photonic crystal T-shaped channel-drop filter is investigated by the finite element method

in which the effects of the refractive index of the dielectric rods on the resonant frequency and normalized transmission are analyzed.On this basis

a filter model for the narrowband photonic crystal filter is designed.The numerical simulation results demonstrate the approximately linear dependence of the inner dielectric rods refractive index on the central wavelength of the drop waveguide output of the narrowband filter

which presents theoretical reference for the design and manufacture of photonic crystal filter.
