利用分步傅里叶方法数值研究了分布拉曼放大对光孤子时间特性的影响，并与二次谐波频率分辨光门控分析仪测量的实验数据进行了比较。计算结果与实验数据吻合较好。可以补偿光纤损耗的色散补偿器不改变孤子的时域波形。在考虑光纤损耗和不同的拉曼增益时，孤子宽度随传输距离的变化呈现不同的振荡。随着拉曼泵浦功率的增加，光纤损耗的补偿效果也随之增加。
The effects of distributed Raman amplification (DRA) on temporal characteristics of an optical soliton that are numerically investigated by using the split-step Fourier method are compared with the experimental data measured by employing the second-harmonic generation frequency-resolved optical gating analyzer. It is found that the numerical results are consistent with the experimental data. DRA that can compensate the fiber loss does not change the temporal wave form of the soliton. The soliton width performs a various oscillation with propagation distance when considering the fiber loss and different Raman gain. Compensation of the fiber loss increases with the increase of the Raman pumping power.
