摘要
本文从MNLS方程出发,采用变分法,导出了在小损耗情况下超高斯脉冲参数随传输距离的演化方程组及其解,讨论了小损耗对光纤中超高斯脉冲传输特性的影响。
The MNLS equation and variational method are used to derive the evolution equations for the parameters of the super-gaussian pulse and their solutions.The influence of the small dielectric loss on the propagation properties of super-gaussian pulses in fibers is discussed.
