| 摘 要： | 本文在考虑群速度色散(GVD)、受激喇曼散射(SRS)、自相位调制(SPM)、交叉相位调制(XPM)及光纤损耗同时作用的条件下,建立了关于单模光纤中喇曼类孤子的理论计算模型。通过模拟计算Gouveia-neto等人的实验,得到了84fs的喇曼类孤子脉冲,与其实验结果基本一致,并给出了喇曼类孤子脉冲形成过程的图象和新见解。

| Abstract: | We present a unique theoretical model to describe the Raman soliton-like pulses in single-mode fibers and consider the existence of the group velocity dispersion (GVD), the stimulated Raman scattering (SRS), the self-phase modulation (SPM), the cross-phase modulation (XPM) and the fiber loss. The experiment made by Gouveianeto et al. is simulated and 84fs Raman soliton-like pulses are obtained in agreement with the experimental results. A distinct image of the evolution of Raman soliton-like pulses is abtained and some new ideas are put forward. |
