光纤损耗对皮秒脉冲孤子效应压缩的影响

在计及常规光纤损耗的前提下，通过数值求解求解修正的非线性薛定谔方程，全面地计算和分析了损耗对皮秒脉冲在单模光纤中孤子效应压缩过程的影响。结果表明，与不计及损耗时相比，损耗一方面导致脉冲压缩比，压缩后的脉冲峰值功率和脉冲压缩质量的下降，另一方面还导致所选用的最佳光纤度的增加。进一步研究表明，损耗对脉冲压缩的影响程度还与输入脉冲的峰值功率和脉宽有关。

Effect of fiber loss on soliton-effect picosecond pulse compression in optical fibers

The effect of fiber loss on the quality of soliton-effect picosecond pulse compression is analyzed by solving the modified nonlinear Schrodinger equation numerically. The results show that fiber loss affect the performance of soliton-effect pulse compressors both qualitatively and quantitatively. The compressed pulse is longer with a lower peak power and a poorer pulse quality when fiber loss is taken into account. Furthermore, the optimum fiber length for maximum compression is longer than that expected in the absence of fiber loss. The effect of fiber loss on compression quality relates not only to the initial peak power but also to the initial pulse width.
