The Physics Society of Iran Iranian Journal of Physics Research 1682-6957 4 3 2019 11 26 One-dimensional optical spatial screening solitons in photorefractive media and incoherent interaction between them One-dimensional optical spatial screening solitons in photorefractive media and incoherent interaction between them 255 266 703 FA F. A. Keshavarz A. Zakery Journal Article 2019 11 26   Optical spatial screening solitons in photorefractive crystals in a one-dimensional case based on Kukhtarev model is studied. The new numerical scheme according to the Crank-Nicholson method accompanied by the central difference method is introduced to find the bright soliton solution. Simulation of the propagation is performed to show the dynamical evolution of solitons and check their stability. Numerical investigation of the interaction between incoherent screening photorefractive solitons is also performed. The influence of intensity and initial separation of the mutually incoherent self-trapped beams are discussed in detail.   Optical spatial screening solitons in photorefractive crystals in a one-dimensional case based on Kukhtarev model is studied.
