Abstract
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, bright-bright and bright-dark screening soliton pairs in centrosymmetric photorefractive crystals are possible due to photorefractive effect.
