We investigate the dynamics of multiple two-wave mixing in photorefractive materials. This is
the first time to our knowledge that a study of the dynamics of many pairs of two-wave mixing …

Steady-state dark photorefractive spatial screening solitons are observed in an odd-or even-
number sequence when a laser beam that contains a dark stripe generated from a phase or …

We investigate propagation of light beams in photorefractive media by direct numerical
simulation. The two dimensional model is based on solution of nonlinear material equations …

We investigate light diffraction in a direction perpendicular to the surface of a photorefractive
crystal by anisotropic or isotropic Bragg diffraction. We estimate the resolution limit by …

We report a theoretical model for a photorefractive running hologram in bulk-absorbing
materials in the presence of self-diffraction and use this model to analyze experiments for …

The initial holographic recording rate has been analytically studied for a photorefractive thin
slab. The finite thickness is explicitly taken into account by using a two-dimensional …

We report on the observation of switching and self-pulsing of guided modes in a planar
lithium niobate waveguide due to the photorefractive formation of holographic gratings. The …

The self-bending process of steady-state bright spatial solitons in biased photorefractive
media is investigated by taking into account diffusion effects. By integrating numerically the …

We propose a mathematical model for the movement in absorbing materials of
photorefractive holograms under feedback constraints. We use this model to analyze the …
