Abstract
We experimentally observed the self‐channeling of the light beam in photorefractive Bi12TiO20 fiberlike sample owing to the strong fanning effect. It results in significant speed up of the photorefractive response time in waveguides and in anomalous dependence of the response time on the applied acelectric field amplitude: the higher electric field, the faster response.Keywords
