The generation of (1+ 1)-dimension photorefractive spatial dark solitons by 180° phase or amplitude jumps is reported. Experiments are performed in a cubic photorefractive …
This paper presents a way to achieve optical limiting using the self-focusing of a laser beam in a photorefractive medium. In this view, the protection is not based on the absorption of the …

We report the observation of steady-state photorefractive vortex-screening solitons. As a singly charged circular vortex nested on a broad beam propagates through a biased …

We have obtained stationary bright spatial solitons in a planar photorefractive strontium barium niobate waveguide for visible light ranging from 514.5 to 780?? nm. Even for larger …

A well-defined ring of anisotropically scattered light is observed when a linearly polarized laser beam is incident upon a birefringent photorefractive crystal such as BaTiO_3 …
We show that optically induced photonic lattices in a nonconventionally biased photorefractive crystal can support the formation of discrete and gap solitons owing to a …

The question of spiraling or no spiraling of incoherent screening spatial solitons in photorefractive crystals is addressed by a careful numerical analysis. We find that the …
We investigate experimentally the interaction of two-dimensional solitary beams in photorefractive strontium barium niobate crystal. We show that simultaneous collision of …
