基于双光子光折变效应的中心对称亮空间孤子的自偏转
The Self-deflection of Centrosymmetric Bright Spatial Solitons based on the Two-photon Photorefractive Effect
摘要
基于外加电场的双光子中心对称光折变介质,数值研究了中心对称亮孤子的自偏转特性。结果表明：具有双光子效应的中心对称光折变介质中,亮孤子在扩散效应的作用下呈现出与光轴方向反向的自偏转特性;孤子中心偏转距离与外加电场和入射光强等参量相关。随着外加电场的增加,孤子的自偏转距离逐渐加大。亮孤子自偏转距离随着入射光强的增加表现出先增加后减小的非线性变化规律,在孤子半峰全宽最窄处,孤子的自偏转距离存在一最大值。
