Abstract

Propagation of optical beams and properties of one-dimensional (1D) spatial solitons in photorefractive planar waveguide are analyzed. The waveguide contains an AlGaAs/GaAs multiple quantum well guiding layer biased with an external electric field along the quantum well planes. An approximate dependence of the refractive index changes on the local beam intensity is derived. An analytic solitary solution of the corresponding propagation problem is presented.
