Abstract
Two-wave mixing in photorefractive InP:Fe crystals is revisited considering an externally applied dc field combined with the moving grating technique. We show that the disagreement previously observed in the literature between theory and experiments finds an explanation in the influence of both the absorption along the propagation axis and the nonlinearities occurring at relatively large fringe modulations. A finite difference method is used to demonstrate the dependence of these nonlinearities on the average incident intensity.
