| 摘 要： | 分析了光纤光栅色散补偿系统中的串扰，并比较了几种常用的多波长光纤光栅色散补偿器的串扰特性，结合串联的窄带光纤光栅和取样光纤光栅的优点，提出一种抑制光纤光栅色散补偿系统串扰的方法.它通过在邻近信道间引入随机时延差，既能改善取样光纤光栅的线性串扰特性，又能抑制交叉相位调制效应和四波混频等非线性串扰.使用该方法可以得到具有低串扰的多波长光纤光栅色散补偿器.

| Abstract: | A novel method is proposed to suppress the crosstalk of the DWDM system with dispersion compensated by fiber gratings, combining the merits of both concatenated narrowband fiber gratings and sampled fiber gratings. Random time delay is induced only between the adjacent channels to improve the characteristics of fiber gratings' linear crosstalk, with the cross modulation effects and the four wave mixing effects being suppressed simultaneously. Using this method,we can realize the low crosstalk multi-wavelength dispersion compensators based on fiber gratings. |
