级联马赫曾德尔干涉仪光学梳状滤波的理论
Theoretical Study on Optical Comb-Filter of Cascaded M-Z Interferometer
摘要
提出一种级联马赫曾德尔光纤干涉仪,它是采用多个3 dB耦合器串联而成的。模拟与分析表明,当光纤干涉臂长度差ΔL按顺序取一系列定值时,将得到性能良好的梳状出射谱图。其干涉峰的边模抑制比随干涉臂数目的增多而变大。
Abstract
A cascaded M Z fiber interferometer has been analyzed,which is made of several 3 dB couplers in series. Theoretical analysis and numerical simulation indicate that a good comb-like curve will be obtained when the length difference Δ L of interference arms is given by a certain value in order. SSR will increase as adding of the number of interference arms.
