title: Circular waveguides induced by two-dimensional bright steady-state photorefractive spatial screening solitons.
abstract: We report what we believe is the first experimental observation of bright-soliton-induced two-dimensional waveguides. The waveguides are induced by two-dimensional photorefractive screening solitons, and their guiding properties, i.e., whether the waveguides are single mode or multimode, are controlled by adjustment of the soliton parameters.
