摘要:
We experimentally observed the self‐channeling of the light beam in photorefractive Bi12TiO20fiberlike 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 ac electric field amplitude: the higher electric field, the faster response. ©1995 American Institute of Physics.
