摘　　要：应用付里叶变换法,求解了非线性薛定谔方程,得出了单模光纤在正、反常色散区域中二阶群速度色散(GVD)效应所致啁啾的解析表达式。讨论了自相位调制(SPM)所致的非线性啁啾的频移特性。得出了在反常色散区域实现光脉冲无啁啾稳定传输的条件。Taken into account both second order dispersion and SPM in the abnormal-dispersion region of single-mode fibers, we obtained the expression of chirp induced by GVD and SPM. The results show that the feature of chirp changes obviously with the altering N. We may obtain stability of Zero-Chirp pulses in the propagation.
