Analytical solution for photorefractive screening solitons
نویسندگان
چکیده
We study formation and interaction of one-dimensional screening solitons in a photorefractive medium with sublinear dependence of the photoconductivity on light intensity. We find an exact analytical solution to the corresponding nonlinear Schrodinger equation. We show that these solitons are stable in propagation and their interaction is generic for solitons of saturable nonlinearity. In particular, they may fuse or "give birth" to new solitons upon collision.

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 stabi...
متن کاملSpatial soliton pairs in an unbiased photovoltaic-photorefractive crystal circuit
: Optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (PR) crystal are investigated. Each crystal can be supported the spatial soliton, and at least one must be photovoltaic. The two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...
متن کاملPrimarily isotropic nature of photorefractive screening solitons and the interactions between them.
We present experimental evidence demonstrating that the photorefractive-index change responsible for the formation of photorefractive spatial screening solitons and coherent collisions between them is primarily isotropic in nature, even though the photorefractive medium is inherently anisotropic.
متن کاملOptical control of arrays of photorefractive screening solitons.
We discuss the creation of an array of 9 x 9 photorefractive spatial screening solitons in a strontium barium niobate crystal. We investigate the waveguide properties of each channel with a beam of different wavelength and find that the waveguides guide the probe beam independently. A supplementary beam is used to influence the paths of the array solitons and to effectively combine two channels...
متن کاملExperiments on partially coherent photorefractive solitons
We provide an overview of experimental studies on partially coherent spatial solitons in photorefractive materials, including the first experimental demonstration of bright and dark incoherent solitons, incoherent vortex solitons, Y-junction dark solitons and anti-dark solitons, and pixel-like incoherent soliton arrays. These solitons are created with partially spatially incoherent light beams ...
