| 摘 要： | 本文解析地研究初始注入光纤的带啁啾Sech形脉冲(1≠N<3/2)的演化特性。在文献5的基础上,主要利用变分原理,同时把高阶色散项作为摄动项,近似求解了脉冲振幅、脉宽以及频率啁啾参数随传输距离的演化方程。结果表明,高阶色散有助于光纤中渐近孤子的形成。

| Abstract: | The evolution of initial chirp-sech-pulse in optical fiber is analytically investigated in this paper. Starting from reference 5, the changes of amplitude, wideth, frequency chirp parameter with transimition distance is obtained by using variational approach and regarding high-dispersion as a puterbation. The results show that the positive high-dispersion has contributed to the formation of asymptotic soliton in the optical fiber. |
