| 摘 要： | 基于四端口谐振腔滤波理论，采用时域有限差分法(2D—FDTD)对环行谐振腔的滤波特性进行数值仿真，仿真结果给出多模干涉(MMI)耦合长度与滤波特性的关系．所制作的两种GaAlAs／GaAs平面波导环形谐振腔窄带滤波器的测试结果与仿真结果符合较好．

| Abstract: | Based on the theory of four-port resonant filters, the characteristics of filters with ring resonators were numerically simulated by using two-dimensional FDTD method. The relationship between the coupling length of MMI and the filtering features was also simulated . Two narrow-band filters with ring resonators based on GaAlAs/GaAs planar waveguide were designed and fabricated. The measurement on filtering feature was carried out. It coincides well with that from the numeric computation. |
