11 October 1999Evolution of bright screening-photovoltaic spatial optical solitons
The dynamical evolution of bright screening-photovoltaic (SP) spatial optical solitons in biased photovoltaic- photorefractive materials is investigated under steady-state condition. Our numerical study indicates that these SP solitons are stable against small perturbations whereas optical beams that significantly differ from soliton solutions tend to experience larger cycles of compression and expansion.
