Study of Soliton Transmission and Coupling in Heat-lens Effect of Photorefractive Crystal

借助耦合非线性薛定谔方程,分析了光折变晶体热透镜效应中光孤子传输与耦合特性。研究结果表明:光折变晶体热透镜效应的实质就是光孤子耦合的结果,而光孤子传输与耦合的特性与光孤子的相对位相密切相关。

Properties of soliton transmission and coupling in heatlens effect of photorefractive crystal are analyzed.The results show that the essence of heatlens effect in photorefractive crystal is a result of solitor coupling,and the properties of soliton transmission and coupling are related to the relative phase between input solitons.Key Words:photorefractive crystal;heatlens effect;soliton transmission and coupling
