摘要
提出用 3dB耦合器和光纤环镜制作了一种全光纤迈克尔逊 萨尼克型光学梳状滤波器 ,其信道间隔为 5 0GHz。实验研究了其电调谐特性及干涉臂的扭转对其输出特性的影响。对全光纤迈克尔逊 萨尼克型梳状滤波器与马赫 曾德尔干涉仪型梳状滤波器的性能优劣进行了分析比较 ,其结果可以为今后该器件的制作及关键技术的解决提供参考。
A novel comb filter based on all fiber Michelson-Sagnac interferometer is proposed. In experiment, the filter with a channel spacing of 50 GHz is made. Its characteristic of voltage tuning and twisting the arm of the interferometer are discussed, respectively. The performance of the filter is analyzed comparing with that of the traditional M-Z interferometer. The results can be helpful in the manufacture of this kind of apparatus and the solution of key technology.
