摘　　要：针对应用于超高速光通信网络中的超窄光脉冲传输问题,理论分析并数值计算了光纤中的三阶色散与四阶色散对超窄脉冲波形的影响,得到了三阶色散影响导致光脉冲前沿产生形变,后沿基本保持不变,四阶色散导致脉冲急剧展宽以及光谱出现旁瓣的结论。The effects of third-order and fourth-order dispersion on ultra-short optical pulse sharp are analyzed theoretically and numerically in ultrahigh-speed optical communication networks.It is concluded that the third-order dispersion deduces deformation in optical pulse foreside but the backside keep unchanged,and the fourth-order dispersion makes optical pulse expand and optical sidelobe occur.
