摘要
本文采用变分法，探讨了三阶色散存在时类明孤子在光纤中的传输特性，导出了类明孤子参数随传输距离的演化方程组，讨论了三阶色散对类明孤子传输特性的影响．
In this paper, we used the variational principle for the optical soliton-like pulses in the optical fiber and introduced the small perturbation of the third-order dispersion to the NLS equation to investigate the evolution of the parameters of the optical soliton-like pulses, and we got the conclusion and the evolution equations for the parameters of the soliton-like pulses in the optical fiber.
