摘要/Abstract

摘要： 利用等效原理对含有负三阶色散的色散缓变光纤非线性薛定谔方程进行处理发现负三阶色散与色散缓变项存在特定关系．并由此进一步证明了负三阶色散有助于色散缓变光纤对孤子的压缩且存在最佳负三阶色散值．文中还对压缩的动态过程进行了分析理论分析结果与数值模拟结果相一致．

关键词: 色散缓变光纤, 负三阶色散, 孤子压缩效应

Abstract: By utilizing the theory of equivalent -effectthe nonlinear Schrodinger equation of FSDD （Fiber with Slow-
ly-decreasing Dispersion） with the negative third-order dispersion was discussed．It is found that the negative third-or-
der dispersion has a certain relation with the slowly-decreasing dispersion termthus proving that the negative third-or-
der dispersion helps to the compression effect of FSDD on solitonand there exists an optimal value of negative third-
order dispersion．The dynamic compression process was also analyzed．The results obtained by theoretical analysis ac-
cord well with those obtained by numerical simulation．

Key words: fiber with slowly-decreasing dispersion, negative third-order dispersion, oliton compression effect
