Abstract :
Summary form only given. Self-trapping of 1D and 2D optical beams in photorefractive InP has been experimentally observed back in 1996. Here we present the first theory describing the resonant self-focusing effects in photorefractive semiconductors. The theory is based on a models that relies on two donors levels, one deep trap level and conduction of both electrons and holes.
