| 摘 要： | 基于连续波背景上的小振幅近似，研究了自变陡效应对正常色散区和非常色散区孤波传输动力学的决定作用。在计及损耗和增益，以及Ｒａｍａｎ自泵的光纤中，两种色散区中均存在明孤波和暗孤波，尤其是发现了与通常明、暗类型相反的小振幅明、暗孤波。

| Abstract: | Based on the small-amplitude approximation on a CW pedestal, the role of self-steepening effect in nonlinear dynamics and transmmision of soliton in normal and anomalous dispersion regions is investigated. The results show that, by taking into account the loss and gain, as well as the self-induced Raman effect, there exist both bright and dark small-amplitude solitons in both normal and anomalous dispersion regions. Especially, there exist the types of solitons opposite to the ordinary types of bright or dark solitons in both regions. |
