摘　　要：通过求解非线性薛定谔方程,研究了线性光纤中色散导致的具有初始频率啁啾的高斯脉冲展宽的详细物理过程。得到高斯脉冲在光纤中色散所致的脉冲展宽的特性,啁啾因子对脉冲展宽的影响,并讨论了光纤色散对不同宽度脉冲的影响,对色散补偿等技术的研究具有一定的参考价值。The detailed physical process of the group-velocity dispersion-induced initial frequency chirped Gaussian pulses broadening is studied through solving non-linear Schrodinger equation. The characteristics of dispersion-induced pulses broadening of Gaussian pulses in fiber and the effects of pulses broadening on chirp factor are obtained. The pulses broadening of varied pulses width based on fiber dispersion are discussed. This has many helpful values for dispersion compensation.
