摘要

文章数值分析了负色散掺铒光纤放大器（EDFA）中基孤子脉冲传输及啁啾特性

基孤子脉冲在EDFA中传输能够获得很好的线性啁啾

并且啁啾的特性受选取的EDFA长度L的影响

L越大时线性啁啾越明显

线性啁啾所占的脉冲区域越窄。最后计算了输出脉冲在啁啾补偿后获得的压缩因子和基座能量比。

Abstract

The propagation and chirp characteristics of the fundamental soliton pulse in the Erbium-Doped Fiber Amplifier（EDFA） in the anomalous-dispersion regime are numerically studied and a novel method for achieving linear chirp by using EDFA proposed.The results of the numerical analysis show that good linear chirp is obtained when the gain coefficient μ is far greater than 1 and the chirp characteristics are affected by the length L of the selected EDFA: the larger the value of L

the more obvious the linear chirp

but the narrower pulse region it takes.Finally

the compression factor and pedestal energy ratio of the output pulse obtained after chirp compensation are calculated.
