【摘要】 对光折变有机聚合物中的双色光空间孤子进行了理论分析 ,证明双色信号光的两个频率成分相互作用可以在折射率改变为正的光折变有机聚合物中形成暗暗和亮暗空间孤子 ,在折射率改变为负的光折变有机聚合物中形成亮亮和亮暗空间孤子。与单色光孤子的情况不同 ,对于双色光孤子情况 ,通过与一形成暗孤子的频率成分相互作用 ,另一频率成分在折射率改变为正的有机聚合物中也可形成亮孤子 ;通过与一形成亮孤子的频率成分相互作用 ,另一频率成分在折射率改变为负的材料中也可形成暗孤子更多还原

【Abstract】 The theoretical study shows that the two frequency components of a polychromatic light can interact each other in photorefractive polymers, and the bright-bright, dark-dark and bright-dark polychromatic spatial soliton solutions for optical wave evolution equations are presented under some steady-state conditions. A bright soliton can be formed in the photorefractive polymers with positive refractive index perturbation supported by a proper dark soliton, and a dark soliton can be formed in the photorefractive polymers with negative refractive index perturbation supported by a proper bright soliton.更多还原
