摘　　要：根据最近研究的一种改进型光纤Mach-Zehnder干涉仪(MZ1)型Interleaver存在的问题,提出一种改善其滤波特性的新结构．对其原理和相关参数进行了模拟分析,结果表明新结构的光谱形状与隔离度都比原结构有较大改善,且保持了信道的对称性．本文分析计算的结果对器件的优化设计具有实际的指导意义．A novel design of interleaver based on Mach-Zehnder interferometer is semonstrated in this paper. The theoretical analysis and the simulation results show the perfect performance of the new architecture. Compared with other designs of interleaver, the new architecture with high isolation has a fiat-top passband, and its old channels and even channels keep in symmetry. Also, the feasibility of this kind of design is studied.
