The diffraction properties of fixed volume gratings, including the effect of additional
photorefractive energy coupling between the incident wave and the diffracted wave, are …

We consider the diffraction properties of index gratings in photorefractive media, assuming
an arbitrary momentum mismatch (Bragg mismatch). The incident and diffracted waves …

We present two analytical methods of solving the coupled wave equations related to two-
wave mixing in a photorefractive medium in the case where the illuminating light pattern is …

We present a new approach to measure the phase shift between the photorefractive grating
and the interference pattern in two-wave-mixing experiments. This approach is based on …

We present measurements of the two-wave mixing gain as a function of frequency detuning
in photorefractive crystals. In many cases, this function is asymmetric, indicating that the …

We present a simple shooting method to obtain numerical solutions of the nonlinear coupled-
wave equations for degenerate four-wave mixing in photorefractive crystals when four …
