摘要

针对密集波分复用系统中多信道色散补偿问题

文章首先采用传输矩阵法对取样光栅进行了分析

然后介绍了在此基础上通过调节线性啁啾系数所进行的仿真实验。仿真结果表明

在多信道色散补偿中

啁啾取样光栅反射谱的反射率非常均匀

且都达到了90%以上;时延谱具有很好的一致性

最小时延抖动<40ps;色散图也比较均匀

能完成正负色散的补偿

且在仿真中色散值可以不超过500ps/nm。

Abstract

For multi-channel dispersion compensation in DWDM systems

this paper first analyzes the sampled fiber grating by using the transfer matrix method and on this basis carries out simulation experiments by regulating the linear chirping coefficients.The simulation results indicate that in the multi-channel dispersion compensation

the reflective spectra of the chirped sampled fiber grating are uniform and all the reflectivities are above 90%;that the delay spectrum is consistent and the minimum delay jitter is smaller than 40ps;and that the dispersion diagram is also uniform and can compensate both the positive and negative dispersion

and in the simulation

the dispersion value does not exceed 500ps/nm.
