Incoherent Interaction Between Bright–Bright Photovoltaic Soliton in an Unbiased Series Two-Photon Photorefractive Crystal Circuit: Self-Deflection Investigation

We investigated the effects of self-deflection on incoherent interaction between photovoltaic bright–bright soliton pairs in photorefractive crystals under steady-state condition in an unbiased series two-photon photorefractive crystal circuit in one dimension. The numerical schemes according to the Crank–Nicholson and Runge–Kutta methods are applied to simulate the propagation of incoherent interaction for studying self-deflection by considering the diffusion process with different normalized separation distances, different amplitude and different δ. We also offer some applications about this subject.
