Manakov Solitons in Biased Two-photon Photovoltaic Photorefractive Crystals

本文从理论上研究了有偏压的双光子光伏光折变晶体中非相干耦合屏蔽光伏Manakov空间孤子对;推出了有外加电场的双光子光伏光折变介质中的亮-亮、暗-暗和亮-暗Manakov孤子解,并对Mana-kov孤子对的特性进行了详细的讨论.

A theory on the incoherently coupled screening-photovoltaic Manakov solitons pairs in biased two-photon photovoltaic photorefractive crystals is investigated.The result shows that when the total intensity of two coupled solitons is much lower than the effective dark irradiance,the coupled solitons equations reduce to the Manakov equations.The dark-dark,bright-bright and bright-dark soliton pair solutions of these Manakov equations are obtained under an appropriate external bias field and a photovoltaic filed,and the characteristics of these Manakov soliton pairs are also discussed in detail.
