摘要
给出了三阶色散对高斯脉冲传输影响的方程和传播图形.利用计算机数值模拟的方法,研究了光纤通信中三阶色散对双曲正弦高斯脉冲在光纤中传输的影响.模拟结果表明,群速度色散的存在导致了脉冲迅速展宽并形成振荡,而三阶色散导致了双曲正弦高斯脉冲的2个脉冲变得不对称.
Equation and transmission image of impacts of three-order dispersion on hyperbolic sine Gaussian pulse transmission were given in this paper. Method of computer numerical simulation was used to research impacts of hyperbolic sine Gaussian pulse transmitting in the optical fiber. The simulated results indicate that existing of group velocity causes rapid broadening of pulse and form vibration, while three-order disper- sion causes two of hyperbolic sine Gaussian pulses asymmetric.
