Analytical modeling of two beam coupling during grating translation in photorefractive media
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 rapidly translated with respect to a stationary photorefractive grating. Both methods lead to the same analytical expressions for the intensities of the transmitted beams and for the initial phase of their temporal oscillations.
Our analytical expressions cannot, however, confirm earlier numerical and experimental results obtained by Grunnet-Jepsen et al. [Opt. Lett. 22 (1997) 874] regarding the photorefractive phase shift in photorefractive polymers.
