摘要
在标准非线性薛定谔(NLS)方程中引入光纤的小损耗项和三阶色散项,利用变分微扰法,导出了类明孤子脉冲的参数演化动力学方程组,讨论了小损耗和三阶色散对类明光孤子脉冲传输特性的影响.
The small dielectric loss and third -order dispersion of optical fiber are introduced in the standered NLS equation and the evolution of the parameters of the optical soliton - like pulse is investigated by using the variational principle and perturbation method. We discuss the influence of the small dielectric loss and third - order dispersion to the propagation properties of soliton - like pulses.
