摘要

利用CIP方法模拟了三角形晶格二维柱型光子晶体波导的传输和滤波特性。在3.6 ~ 4.2 GHz微波频率范围内，用比例模型对y型支路和级联1X4型支路波导的仿真结果与实测结果进行了比较。对不同长度空腔的谐振特性进行了观测，与实验结果吻合较好。该结构适用于光或微波通信系统中作为波分复用(WDM)系统的基本滤波元件。

Numerical Analysis of 1X4 Branch Waveguide in Two Dimensional Photonic Crystal Structure

Propagation and filtering characteristics of two dimensional (2D) pillar-type photonic crystal waveguide with triangular lattice were simulated by CIP method. The simulation results for Y-shaped branch and the cascaded 1X4 Yshaped branch waveguide were compared with measurements by using a scale model in microwave frequency range from 3.6 to 4.2 GHz. The resonant characteristics for cavities with various lengths were observed in good agreement with the experiment. This structure is applicable as a basic filter component in wavelength division multiplexing (WDM) systems in optical or microwave communication systems.
