摘要:

分析了色散管理孤子的基本原理和特性,并通过数值计算对色散管理孤子的传输过程中的孤子互作用进行了模拟。发现在色散管理光纤链路中,如果平均色散与本地色散差异较小,色散管理孤子最好取双曲正割形,孤子互作用表现为非线性互作用;如果本地色散和平均色散差异逐渐变大,色散管理孤子波形向高斯形变化,色散逐渐成为影响孤子互作用的主要原因。

Abstract:

Examed the properties of dipersion-managed soliton. Dispersion-managed soliton propagation and interaction in optical fibers is simulated by numerical calculation.It is noticed if there is little difference between local dipersion and average dispersion,it is better to insert the pulse with shape as hyperbolic secant;if increase the differences of local dipersion and average dispersion, the shape of the pulse transformed as gauss.Dispersion become the main factor of dispersion-managed soliton interaction.

Key words: optical communication, soliton interaction, numerical simulation, local dispersion, average dipersion
