摘要
在准理想的色散管理系统中建立了非均匀扰动模型 ,研究了它们对孤子传输和相互作用的影响 这些扰动导致孤子崩塌 ,加剧了孤子间相互作用 它们影响的大小与周期长度和扰动强度有关 ,并且存在最坏周期长度和扰动共振现像 最后 。
Models of periodically inhomogeneous perturbations are made reasonedly in a quasi ideal dispersion managed soliton system, their effects on soliton propagation and soliton interaction are investigated. These perturbations lead to disintegration of soliton, and enhance soliton interaction. Their effects relate to period lengths and strengths of perturbations, and there are the worst period lengths and resonance between two perturbations for soliton propagation and soliton interaction. Finally the nonlinear gain and filter are introduced to suppress effectively these effects.
