本文利用非线性薛定谔方程,通过数值模拟,分析了三阶群速度色散和初始啁啾对超高斯脉冲传输的影响.结果表明三阶色散效应会引起光脉冲的脉宽展宽、脉幅下降、脉冲畸变和振荡拖尾等畸变,降低输出的信噪比,导致光信号传输质量的下降.%This paper analyzed impact of third order group velocity dispersion and initial chirp on the super-Gaussian pulse transmission by the non-linear Schrodinger equation and the numerical simulation.The results show that the pulse width of optical pulse is broadened, pulse amplitude is decreased, pulse is distorted, oscillation is streaked, outputted signal to noise ratio is reduced, and transmission quality of optical signal is declined,caused by the third-order dispersion.
