K. Kos et al., ONE-DIMENSIONAL STEADY-STATE PHOTOREFRACTIVE SCREENING SOLITONS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 53(5), 1996, pp. 4330-4333
We study one-dimensional steady-state photorefractive screening solito
ns in a bulk strontium barium niobate crystal. We compare measurements
and calculations of the soliton properties and find good agreement fo
r relations between the profile, width and intensity of the soliton, t
he applied voltage and material parameters. We find the solitons stabl
e against perturbations both in the plane and perpendicular to the pla
ne of the soliton for intensities large compared to the background int
ensity.
