Analysis of wave coupling in photorefractive cubic media far from the paraxial limit

Research output: Contribution to journal › Journal article › Research › peer-review

Abstract

A rigorous three-dimensional theoretical description of the two-wave mixing processes in cubic crystals is presented. The theory includes linear birefringence, self-diffraction, and optical activity. Comparisons have been made with previously developed theories that use the paraxial approximation, and significant deviations have been observed. It is shown that in the case of two-wave mixing in Bi₁₂SiO₂₀ for grating fringe spacings below 0.4 µm the exact model that we describe should be used.
