摘　　要：研究了自陡峭效应对不同群色散剖面色散缓变光纤中调制不稳定性的影响,结果表明:不同类型的色散缓变参数均存在某一最佳值,在此值下增益谱的谱宽最宽,而当色散缓变参数大于某一值时,增益谱宽为0.The effect of self-steeping on the modulation instability in decreasing dispersion fiber with different group dispersion profiles is investagted. The result shows that different DDF have different optimal values, under which the gain spectrum is the broadest, and the gain spectrum is 0 when the decreasing dispersion parameter is bigger than a certain value.
