摘要
文章从含修正项的非线性薛定谔方程出发,采用变分法,导出了单模光纤中小损耗情况下,基黑孤子脉冲参数随传输距离的演化方程组;并导出了光纤中小损耗对基黑孤子脉冲传输特性的影响。
Starting from the nonlinear Schrodinger equation with correction term,the equations showing the evolution of fundamental black soliton pulse parameters with the transmission distance under the small dielectric loss in single-mode fibers were demonstrated by variation method.This paper also discussed the influence of small dielectric loss in fiber on the transmission features of fundamental black soliton pulse.
