摘要
提出了研究有介电常数扰动的光纤中的孤子动力学行为的数值方法——修正Split—stepFourier法。重点讨论了扰动是正弦函数形式时,耦合强度、频率、波数、初始相位差对光孤子传播的影响。
In this paper, we present a modified split-step Fourier method, which is used to study the dynamic behavior of optical soliton in the optical fibre with arbitrary perturbation of the dielectric constant. This paper focuses on the perturbation which takes the sine form. The effect of amplitude, frequency, wave number, and initial phase difference on the propagation of optical soliton is investigated.
