摘　　要：分析了光纤光栅的色散特性,介绍了利用均匀光纤光栅透射色散特性进行色散补偿的原理,对级联光纤光栅用于波分复用(WDM)系统多信道色散补偿进行了数值模拟和分析.结果表明,通过选择适当的光纤光栅参数,级联光栅能够对WDM系统中由于常规光纤而色散展宽的光脉冲进行有效的色散补偿.The dispersive properties of the single and cascaded fiber gratings have been discussed and analyze.A transmission-based dispersion compensator employing cascaded fiber gratings for dispersion compensation of multiple channels WDM lightwave systems has been proposed correspondingly in the paper.The results show that the effective compensation can be achieved if the parameters of cascade fiber gratings are chosen carefully.
