摘　　要：本文采用变分法和数值方法研究了具有随机色散的光时分复用系统中色散管理孤子相互作用.发现随机色散增强了孤子间相互作用,产生了导致孤子淹没的振幅和间隔涨落.相互作用距离与初始间隔、初始相对相位、脉宽和初始相对振幅有关.Dispersion-managed soliton interaction is investigated in an optical time-division multiplexed system with random dispersion map by the variational approach and the numerical simulation. It is found that the perturbation caused by random dispersion map enhances the interaction between neighboring solitons, and results in fluctuations of amplitude and separation which submerge solitons. The interaction distance relates to the standard deviation, the initial relative phases, the pulse width and the relative amplitude.
