The inteal modes of incoherent vector solitons (IVSs) in photovoltaic photorefractive materials are investigated in the framework of coupled nonlinear Schr(o)dinger equations. It is found that there is a pair of inteal modes corresponding to a bright-bright IVS. The propagation dynamics of the bright-bright IVS perturbed by the inteal modes is simulated by numerical method.
