摘要
本文研究了单模光纤中两个飞秒量级弧子之间的相互作用。由于拉曼散射的作用,两个孤子的能量重新分布,最终演化成在时域上有一定延迟,分开的两个“新孤子”。通过数值求解高阶非线性薛定谔方程,发现两个飞秒孤子之间的相互作用与输入参数有关,其能量的重新分布由脉冲间的拉曼散射效应,交叉相位调制效应决定。
Interactions between two femtosecond solitons in single- mode optical fibers are studied. Because of Raman scattering, the total energy of the two input solitons is redistributed into two new solitons. The two new solitons are seperated and has delay in time - domain. Numerical simuation are performed through a solution of the generalized nonlinear Schrodinger equation. It is found that the interactions between two femtoseeond solitons relate to various input paramemeters, and the energy redistribution depends on Raman secttering and cross-phase modulation.
