  1. The equation including the nonlinear dispersion, i. e. the modified nonlinear schrodinger ( mnls ) equation, is a better model. in this thesis, we take mnls solitons as a model for femtosecond soltions. then based on the recently developed direct perturbation theory for perturbed mnls equation, we study the raman self - frequency shift of femtosecond solitons and its suppression by the means of frequency filters. for this purpose, first, we define the physical parameters of mnls solitons ; next, through the direct perturbation theory for perturbed mnls equation, under adiabatic approximation, we obtain the evolving parameters of mnls soliton on our questions and then choose the parameters of frequency filters based on it ; at last, we directly numerically simulated our questions by split - step fourier ( ssf ) method after improving the arithmetic of the differentiation of the nonlinear item for satisfying mnls equation

    本論文以mnls孤子作為光纖秒孤子的,通過新近建立的mnls孤子直接微擾理論,研究光纖中拉曼效應引起的秒孤子在傳輸中的頻移,以及通過頻率濾波對頻移的抑制。為此,首先給出描述mnls孤子的各物理量,然後用mnls孤子直接微擾理論,解析地得到這些問題絕熱近似下的孤子參數演化,並此選擇頻率濾波的參數,最後用分步傅里葉方法,在對非線性項微商的演算法做出了適合於mnls孤子的改善後,對拉曼效應及頻率濾波進了直接數值擬,其中頻率濾波參數用微擾理論確定。
