Abstract
We present a numerical and experimental study of vectorial two-wave mixing in cubic photorefractive crystals with nonlocal gratings in the case of strong wave coupling when the grating is not uniform along the propagation direction. We demonstrate that, in important experimental configurations, vectorial two-wave mixing leads to equal intensities and orthogonal polarizations of the interacting waves at the output of the photorefractive crystal. We analyze a bidirectional vectorial light amplification and discuss the effects of the crystal orientation and optical activity. Experimental results of two-wave and multiwave mixing in a Bi12TiO20 crystal with an ac applied electric field are presented.
