二阶孤子相互作用的研究

Study on the Interaction of the Second Order Solitons

本文用等效势的观点,对非线性单模光纤中的二阶孤子间的相互作用进行了理论分析,得出了其相互作用表现为引力,并且引力的大小随孤子间隔的增大而减小的结论。本文还用数值计算法模拟了在不同注入条件下的两个二阶孤子在光纤中的传输情况。结果表明:非等幅注入可以使二阶孤子相互作用减弱。

In this paper the interaction of the second order solitons in nonlinear monomode optical fibers is theoretically analyzed with the view of equivalent potertial. The numerical results show that the initial launching of different amplitudes can decrease the soliton's interaction.
