| 摘 要： | 数值模拟了光纤通信中三阶色散和四阶色散对飞秒光脉冲传输的影响，结果表明三阶色散和四阶色散都会影响通信质量，三阶色散起主要作用，正常色散使光脉冲向前沿偏移，反常色散使光脉冲向后沿偏移，它们都使脉冲展宽且形成振荡带；四阶色散使脉冲展宽且光谱出现旁瓣。

| Abstract: | This paper presented the numerical simulation of the effect of third-order dispersion(TOD) and four-order dispersion(FOD) on femtosecond optical pulse propagation properties in fiber optic communication. The results show that both the TOD and FOD can affect the communication quality: the pulse width will be expanded and the pulse will drift backwards and ahead by the positive and negative TOD respectively, the pulse width will be expanded and the side spectra will be caused by FOD. |
