摘要

文章从描述皮秒光脉冲在色散缓变光纤（FSDD）中所满足的非线性 Schrodinger（NLS）方程出发

数值模拟了高阶皮秒光孤子在不同的 FSDD中的孤子效应压缩

并讨论了初始啁啾对其的影响 .结果表明

利用 FSDD和孤子效应压缩来压缩带有初始啁啾的高阶皮秒光孤子

可以得到更高的压缩比和品质因子

压缩后的脉冲的峰值功率明显提高

而且脉冲被压缩到最窄所需的光纤长度也大大缩短 .最后讨论了初始脉宽的影响 .

Abstract

The soliton-effect of picosecond pulse compression in fibers with slowly decreasing dispersion is studied. In this paper

by soluting the nonlinear Schrdinger equation （NLS） including gain effect numerically

we find that good compression effect will be obtained if initial chirp is added on pulse in optical fibers with slowly decreasing dispersion. Furthermore

the effect of initial width of pulse on soliton-effect of picosecond pulse compression is also obvious.
