Intrasignaling coupling in a LiNbO 3 photorefractive crystal is studied. It is shown that the anisotropy nature of the effective electrooptic coefficient of this crystal results in an orientation‐dependent intrasignal coupling. Analytical solutions for one‐dimensional intrasignal coupling are derived for a‐axis and b‐axis orientations, which enables us to estimate the maximum beam field angle and the maximum crystal thickness for a given intensity distortion due to the coupling. The results are thus illustrative to applications of this crystal in areas such as holographic data storage, interconnection, spatial mode conversion, et cetera. © 1994 John Wiley & Sons, Inc.
