摘要/Abstract

摘要： 为了得到开路光折变聚合物中存在非相干耦合空间孤子对的结果，基于聚合物光折变效应的理论，证明了稳态开路条件下光折变聚合物中存在非相干耦合亮-亮、暗-暗、灰-灰和亮-暗光伏空间孤子对。结果表明：孤子对是由两束偏振方向和波长都相同而且互不相干光耦合形成的。孤子对两光束都能在光伏光折变聚合物中稳定传播。

Abstract: In order to study the incoherently coupled spatial soliton pairs in open-circuit photorefractive polymer, the incoherently coupled dark-dark, bright-bright, grey-grey and bright-dark soliton pairs are predicted in open-circuit photovoltaic photorefractive polymer under steady-state conditions based on the polymer photorefractive effect. The results show that these soliton pairs can be established provided that the carrier beams share the same polarization，wavelength, and are mutually incoherent. When these incoherent coupled soliton pairs propagate together, two components can propagate stably in photovoltaic photorefractive polymer.

Key words: nonlinear optics, photorefractive effect, photorefractive polymer, spatial soliton pairs
