摘要
提出一种将两个光纤环形腔分别加入MZ干涉仪两个干涉射臂中构成的交错复用器,得出了满足DWDM所需滤波性能的两个光纤环形腔的最佳耦合比.理论设计表明,这种新结构与已有的单环形腔的MZ型交错复用器相比,同时具有更宽的0.5dB透过带和25dB截止带.分析了耦合比对滤波性能的影响.
The theory investigation of a flat-top optical interleaver with two ring cavities in a M-Z interferometer is present. We find the optimum coupling angle of the two two ring cavities which meet the needs for DWDM. The result indicates that the interleaver with two ring cavities can simultaneously produce a 0.5 dB passband and a 25 dB stopband wider than with only one ring cavity. Influence on its transmission characteristics by the coupling angle is also analyzed.
