双光子独立明-暗孤子对中暗孤子对明孤子偏转影响

Effects of dark soliton on the deflection of the bright soliton in a two-photon separate bright-dark soliton pair

基于串联双光子光折变晶体回路中一维独立屏蔽孤子对的理论,研究了独立明-暗屏蔽孤子对中暗孤子对明孤子自偏转的影响。数值结果表明:晶体中明孤子以抛物线形式发生偏转,空间漂移随暗孤子的入射强度变化而改变。用微扰法对自偏转的影响进行进一步的研究。这些结果对光控光器件的工程实现具有重要的参考价值。

Based on the theory of one - dimensional separate soliton pairs formed in serial two - photon photorefractive crystal circuit, we investigated the intensity effects of dark solion on the deflection of the bright soliton in a bright - dark pair. Our numerical result show that the spatial shift of the bright soliton changes with the input intensity of dark soliton. These effects are studied by perturbation technique. All the results have great values in the engineering of the light - control optical devices.
