Abstract
Photorefractive wave mixing in a waveguide geometry with nonguided ext ernal pumps has been studied experimentally and theoretically. Guided beam amplification has been obtained in an iron-doped lithium niobate waveguide. Additionally, photorefractive grating couplers that allow t he transverse profile of the decoupled guided beam to be controlled ar e demonstrated.
