Time domain state variable analysis of induced reflection gratings in photorefractive materials

摘要

Abstract: We apply the multilayer rigorous coupled wave theory to analyze reflection gratings in a photorefractive material of an arbitrary thickness. In particular, we study the effect of varying the overall material length over a few thousand grating wavelengths, and also study the effect of layer detuning on reflection grating formation. Furthermore, convergence of the numerical method is rigorously analyzed. !6
