中文摘要：

一篇小说二阶段光谱采用增加的纤维(DIF ) 与一面高度非线性的线性纤维非线性的光环镜子(HNLF-NOLM ) 互连的对数的分散的压缩结构被数字模拟建议并且示威。数字模拟被解决概括非线性的 Schr 实现 ? dinger 方程使用裂口步 Fourier 方法，在 soliton 数字在 0.5N1.4 的范围的地方。系列压缩得好、低柱脚的结果表演，和最大值光谱压缩比率(SCR ) 能到达 10.93 什么时候 N=1.4。

英文摘要：

A novel two-stage spectral compression structure which employs a logarithmic dispersion increasing fiber （DIF） in- terconnected with a highly nonlinear linear fiber-nonlinear optical loop mirror （HNLF-NOLM） is proposed and dem- onstrated by numerical simulation. The numerical simulation is implemented by solving the generalized nonlinear SchrOdinger equation using split-step Fourier method, where the soliton number is in the range of 0.5≤N≤1.4. The re- suits show that the spectra are well-compressed and low-pedestal, and the maximum spectral compression ratio （SCR） can reach 10.93 when N=l.4.
