摘要

理论证明了稳态条件下有分压电阻和e偏振非相干均匀背景光辐照的光伏光折变晶体中存在非相干耦合空间孤子族.这种孤子族是由多束偏振方向和波长都相同的互不相干光束耦合形成的.孤子族各分量成分光束都能在晶体中稳定传播.当入射光束中只含有一个或两个分量时,空间孤子族退化为空间孤子或非相干耦合孤子对.当分压电阻、e偏振背景光、外加电场和光伏场取不同值时,可获得14种光折变非相干耦合空间孤子族.先前已报道的非相干耦合空间孤子族都可在不同条件下从本文中得到.

Abstract: The incoherently coupled soliton families are predicted in photovoltaic photorefractive crystals illuminated by E-polarized incoherent uniform back-ground irradiation with a divider resistance under steady-state conditions. These soliton families can be established provided that the incident optical beams share the same polarization and wavelength, and are mutually incoherent. When these incoherent coupled soliton families propagate together, all components can propagate stably in photorefractive crystal. Moreover, such soliton families reduce into spatial soliton or incoherently coupled soliton pairs when they contain only one or two components. The 14 kinds of incoherently coupled spatial soliton families can be obtained from this theory by adjusting the value of the divider resistance, E-polarized back-ground irradiation, the biased electric field and photovoltaic electric field. Previous theories advanced individually elsewhere for these soliton families can be obtained by simplifying this theory under appropriate conditions.
