| 摘 要： | 从麦克斯韦方程组出发,建立了光脉冲在光纤中传播的理论模型。在只考虑色散效应的情况下,对该理论模型进行进一步的研究,数值模拟出高斯光脉冲在光纤中的传输状态,并讨论了色散对光脉冲传播特性的影响。结果表明,群速度色散会增加光脉冲的宽度而波形保持不变;三阶色散会引起光脉冲的畸变。该结论对光纤的色散补偿具有一定的理论参考价值。

| Abstract: | A theoretic model that describes the propagation of optical pulse in fiber was built proceeding from Maxwell′s equations.A further discussion about this theoretic model is proposed in the case of only considering dispersion.The transmi-ssion state of Gauss optical pulse in fiber was simulated numerically,and the influence of dispersion on transmission characteristics of optical pulse is discussed.It shows that GVD can lead to considerable pulse broadening but keep the pulse shape unchanged,and the TOD can cause pulse distortion.The conclusion has a certain value of theoretical reference on the fiber dispersion compensation. |
