Numerical Investigations of Interactions among Planar Bright Photorefractive Screening Solitons
Detailed numerical investigations of the interactions among planar bright photorefractive screening solitons are performed by employing the so-called beam propagation method (BPM). It's found that two in-phase solitons attract each other,and soliton fusions do occur at certain interaction length,which increases monotonously with the initial separation of the two interacting solitons. While in the case of out-of-phase,the two solitons repel each other with a force decreasing monotonously with the initial separation. When the relative phase between the two solitons falls within the ranges of (0,π) and (-π,0),energy transfer will accompany the interactions. Moreover,interactions among multiple solitons could be qualitatively predicted by analyzing those of the neighboring ones.
