摘要: 基于光纤中孤子传输的支配方程,借助分裂步长Fourier变换法,提出了双源耦合注入准二阶孤子并数值模拟了准二阶孤子与一阶孤子的相互作用,提出并初步论证了基于二阶孤子的三进制光纤孤子通信设想,它能够使中继距离进一步扩大的同时,又使信息量增加log2M-log23=1.6并可降低对光源高功率注入的要求。

Abstract: Based on nonlinear Schrodinger equation, the properties of two-source-coupled-inputed soliton and the interaction between such soli tons and the first order solitons are numerically investigated by the split-step Fourier transformation method. A tentative idea of triply optical soliton communication system is proposed and disscussed, which made the relay distance further extended with the information increased by 1.6 factor. Besides, the high power input of the light source is not necessary by using such solitons.

Key words: optical soliton, numerical simulation, second-order soliton, optical soliton communication
