摘　　要：计算了高斯型脉冲宽度在色散缓变光纤中的传播特性和初始啁啾对脉宽演变的影响。讨论发现:与单模光纤相比,色散缓变光纤中脉冲展宽较慢,并能有效抑制脉冲展宽;初始啁啾对脉宽有较大影响,初始啁啾参量C过大会造成脉冲严重展宽。The propagation characteristics and the influence of initial chirp on Gaussian pulse width were discussed.The results show that comparing to single mode fiber,the pulse in dispersiondecreasing fiber is widened slowly by dispersion.This can effectively restrain the pulse widening.The initial chirp has great influence on pulse width.If the chirp parameter C is too large,it will cause serious pulse widening.
