Abstract

In the present paper, we have studied the dynamics of two spatially separated screening optical solitons in photorefractive-photovoltaic materials incorporating higher order diffusion phenomenon. We have employed paraxial ray approximation method to derive evolution equations of different parameters which characterize the dynamics of two interacting soliton. This approach yields a system of coupled ordinary differential equations for evaluation of solitons parameters such as spatial width and centre of gravity, and subsequently employed numerical method to extract information on their dynamics. Oscillatory stationary bound states predicted, though no stable composite bound state exists..
