| 摘 要： | 基于四端口谐振腔滤波理论，采用二维时域有限差分法（2D-FDTD）数值仿真了矩形谐振腔的滤波特性，分析了串联谐振腔的个数与滤波特性的关系；设计和制作了GaAlAs/GaAs平面波导四串联矩形谐振腔滤波器，获得其滤波特性，测试结果通带半宽约为10 nm；与仿真结果有着较好的符合。

| Abstract: | Based on the electromagnetic model for four port resonant filter, the optical characteristics of several filters with rectangular cascade resonators have been numerically simulated by utilizing two dimensional FDTD method. The relationship between the number of cascade resonators and the filtering features is analyzed. The narrow band filter with four cascade resonators implemented on GaAlAs/GaAs planar waveguide is designed and fabricated. The experiment result shows the half width of filtering spectrum for the chip is about 10 nm, which coincides well with that of the simulation. |
