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。
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.
