摘要
为实现更窄信道间隔的密集波分复用,提出了一种基于偏振光干涉仪的新型Interleaver解复用器,分析了结构组成与基本工作原理,对其进行了初步的测试实验,该器件所分开的DWDM系统两组波长功率均衡,隔离度分别为10.6 dB和14.64 dB,-1 dB带宽分别为0.7 nm和0.4 nm.
Abstract
A novel interleaved demultiplexer based on polarization beam interferometer is proposed. The configuration and basically principle were analyzed by means of birefringence crystal and polarization beam interferometer. With simple experiment, interleaver does separate DWDM odd and even channel into two groups with the power equalization and satisfied with ITU T suggestions. The two channels isolations are 10.6 dB and 14.64 dB respectively, -1 dB bandwidth are 0.7 nm and 0.4 nm, respectively.
