We investigate theoretically and experimentally the operation of a nonlinear system,
feedback controlled photorefractive beam coupling. It is shown that the feedback equations …

We report the experimental observation of steady-state photorefractive Y junctions and
sequences of high-order dark photorefractive screening solitons in a biased bulk strontium …

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 …

In this letter we demonstrate and explain the lack of spatial information crosstalk between
beams in various oscillators by photorefractive CPR) wave mixing (WM). 1, 2 This study is …

The large effective optical nonlinearities available in photorefractive crystals such as barium
titanate, strontium barium niobate, and lithium niobate make them very convenient vehicles …

The concept of optical beam self-trapping in pyroelectric photorefractive medium is
presented. We show that the temperature controlled spontaneous polarisation of …

We study one-dimensional steady-state photorefractive screening solitons in a bulk
strontium barium niobate crystal. We compare measurements and calculations of the soliton …

We demonstrate experimentally second-harmonic generation in waveguides induced by
photorefractive solitons and show that the conversion efficiency is improved considerably …
