含电阻中心对称光折变非相干耦合空间孤子对

摘要

为了得到含分压电阻的中心对称光折变非相干耦合空间孤子对的结果,采用数值模拟方法对这种孤子对的特性进行了理论分析.结果表明,这种孤子埘是由两束偏振方向和波长都相同的互不相干光束耦合形成的.当分压电阻取不同值时,可分别得到有、无分压电阻的非相干耦合屏蔽孤子对.预言了亮-亮,暗-暗和亮-暗非相干耦合空间孤子对可存在于中心对称光折变介质中.%In order to obtain results of incoherently coupled spatial soliton pairs in biased centrosymmetric photorefractive crystal circuit with a divider resistance, the characteristics of these soliton pairs were numerically investigated. The result shows that these soliton pairs are established by the mutually incoherent solitary beams with the same polarization and wavelength. The incoherently coupled screening spatial soliton pairs in biased centrosymmetric photorefractive crystal with a divider resistance or not can be obtained from this theory by adjusting the value of the divider resistance. Incoherently coupled dark-dark, brightbright and bright-dark screening soliton pairs in centrosymmetric photorefractive crystals are possible due to photorefractive effect.
