The existence and nonlinear dynamics of two-component incoherently coupled composite solitons in two-photon photorefractive materials tinder open circuit conditions have been investigated. In the steady-state regime, these incoherently coupled solitons can propagate in bright-dark, bright-bright and dark-dark configurations. These photovoltaic soliton families can be established provided that the carrier beams share the same polarization and wavelength. The influence of the gating beam on the dynamics of stable solitons is discussed. Numerical simulations show that these solitons are stable for small perturbation on amplitude. (C) 2008 Elsevier Ltd.
