受扰动的光纤孤子间的相互作用

基于含扰动的非线性薛定谔方程，发展了高登的光孤子相互作用理论，直接从近似的二孤子解昨到描述实际光纤通讯中孤子间的相互作用的解析公式，公式表明在实际的通讯系统中光纤孤子间的相互作用不令依赖于它们之间相对相差，而且依赖于它们的相对能量，速度差随传输距离的变化。

Interaction Among Perturbed Solitons in Optical Fiber

On the basis of the nonlinear schrodinger equation with the perturbation, the formulas are obtained diretly from the approximative 2 soliton solution to describe the soliton interaction in the practical optical fiber soliton communication. These formulas show that the soliton interaction in practical communication not only depends on their relative phase difference but also on the changes of their energy and velocity difference with the transmission distance. The extended soliton interaction theory can be applied to discuss generally how the perturbations impose effects on the interaction. And the extended theory also can give explanations to the experimental phenomenon about the short-range interaction and long-range interaction reported in Optical letters in 1987, 1989, 1990.
