Primarily isotropic nature of photorefractive screening solitons and the interactions between them.

چکیده
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.

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 کاملInteractions between spatial screening solitons propagating in opposite directions
Collision between solitons is perhaps the most fascinating feature of soliton phenomena, because the interacting self-trapped wave packets exhibit many particlelike features. Over the years, soliton collisions have been extensively studied theoretically and experimentally, in Kerr and saturable nonlinear media, revealing a variety of effects. Among these are elastic and inelastic collisions, fu...
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 کاملIncoherent collisions between two-dimensional bright steady-state photorefractive spatial screening solitons.
We report the observation of incoherent collisions between two-dimensional bright photorefractive screening solitons. The solitons remain intact and do not exchange energy whenever the collision angle exceeds thecritical angle for guidance in the waveguide that each soliton induces, which is, in turn, fully controlled by the soliton parameters. When the collision angle is much smaller than the ...
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...
