| Abstract: | We present a theoretical study on incoherently coupled soliton pairs in two-photon centrosymmetric photorefractive crystals under steady-state conditions. It is shown that the bright-bright, dark-dark and bright-dark Manakov soliton pairs can be generated in two-photon centrosymmetric photorefractive crystals when the total intensity of two soliton components is much lower than the dark irradiance. |
