Filtering Performances of Cascaded Mach-Zehnder Interferometer with Chirped Path Differences

摘要

摘要: 为增大自由频谱区(FSR),优化级联Mach-Zehnder干涉仪(MZIs)的带通滤波性能,利用其与阶梯形滤波器原理的相似性,用啁啾型臂长差替代恒定臂长差.用传输矩阵法建立了臂长差啁啾型级联MZI的数学模型,分析3 dB带宽及FSR的变化规律,验证了理论模型及分析方法的正确性.仿真结果表明,通过合理选取啁啾系数,臂长差啁啾型级联MZI同时获得了较大的FSR和较小的3 dB带宽,且最佳啁啾系数随衍射级数增大而增大.

Abstract: To enlarge the FSR and improve the band-pass filtering performances of cascaded Mach-Zehnder interferometers(MZIs),chirped path differences,rather than fixed path differences,were used based on the similarity between the principles of a cascaded MZIs and a ladder type filter.A theoretical model for cascaded MZIs with chirped path differences was established by transfer matrix method.The variations of 3dB bandwidth and FSR were analyzed.The analysis results show that wider FSR and narrower 3dB bandwidth of cascaded MZIs with chirped path differences can be obtained with an optimized chirp coefficient,and that the optimal chirp coefficient increases with an increase in diffraction order.
