  • In addition , we analyze the amplification absorption and quintic nonlinearity effects on the second solution in the adiabatic approximation
    进而运用微扰理论讨论了当放大器、饱和效应及五次非线性效应存在时,在一个平面波调制下亮孤波的传输特性。
  • 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
    本论文以mnls孤子作为光纤飞秒孤子的模型,通过新近建立的mnls孤子直接微扰理论,研究光纤中由拉曼效应引起的飞秒孤子在传输中的自频移,以及通过频率滤波对自频移的抑制。为此,首先给出描述mnls孤子的各物理量,然后用mnls孤子直接微扰理论,解析地得到这些问题绝热近似下的孤子参数演化,并由此选择频率滤波的参数,最后用分步傅里叶方法,在对非线性项微商的算法做出了适合于mnls孤子的改善后,对拉曼效应及频率滤波进行了直接数值模拟,其中频率滤波参数用微扰理论确定。
