摘要
利用分步傅里叶法数值模拟了飞秒孤子在光纤中的传输演化过程。对光纤中单个孤子的传输及二阶孤子的自陡峭效应和自频移效应进行了分析,指出在一定的参数取值范围内,自频移效应对二阶fs孤子传输的影响要比自陡峭效应大,占主导地位,且对自陡峭效应有一定的抑制作用。
In this paper,the split-step Fourier transform method(SSFM)is used to numerically simulate the propagation of femetosecond(fs)soliton.The single soliton evolution and the effects of self-steeping,self-frequency shift parameter for second order soliton are analyzed.It points out that in a range of the parameters,the self-frequency shift effect is bigger than the self-steeping effect,it is a primary effect in the soliton transmission of fs width,and it can restrain the self-frequency shift effect in a certain extent.
