本文从描述超短光脉冲在色散缓变光纤（ＦＳＤＤ）中传输所满足的准非线性Ｓｃｈｒｏｄｉｎｇｅｒ（ＮＬＳ）方程出发，证明该方程与常规光纤中含增益效应时的ＮＬＳ方程等价，并在此基础上进行了理论分析，讨论了光弧子脉冲在不同ＦＳＤＤ中的传输特性；最后采用数值模拟方法研究了高阶皮秒光孤子在不同ＦＳＤＤ中的压缩效应，发现利用ＦＳＤＤ和弧子压缩效应不但可以获得更高压缩率弧子光脉冲，而且可以有效地缩短所需的光纤长度。
In this paper, we describe the quasi-nonlinear Schrodinger (NLS) equation for the transmission of ultrashort optical pulses in dispersion-slowing fibers (FSDD), and prove that this equation is equivalent to the NLS equation with gain effects in conventional optical fibers. Based on the theoretical analysis, the propagation characteristics of the light-arc sub-pulse in different FSDDs are discussed. Finally, the numerical simulation is used to study the compression effects of higher-order picosecond solitons in different FSDDs. The results show that the FSDD and arc- Not only can get higher compression arc pulse, but also can effectively shorten the required fiber length.
