摘要
为实现更窄信道间隔的密集波分复用 (DWDM) ,设计了一种基于偏振光干涉仪的交错滤波器 (in-terleaver)。该器件可以把 10 0 GHz信道间隔的 DWDM信号光波分成两组 2 0 0 GHz间隔信号 ,各信道功率均衡 ,与 ITU- T建议的波长位置、间隔基本符合 ,通带范围为 C波段 ,隔离度分别大于 2 0 d B和 30d B,- 1d B带宽均为 0 .46 nm。
A novel interleaved filter based on polarization beam interferometer is designed,which applied in close spacings DWDM fiber communications.In experiment,this interleaver does separate DWDM odd and even channel into two groups with the power equalization and satisfied with ITU-T suggestions.Its passband is C waveband,channels isolation are 20 dB and 30 dB respectively,and -1 dB bandwidth are 0.46 nm.The experiment results of 200 GHz-spacings output characteristics are reported simultaneously.
