We present an analytical theory of vectorial wave coupling in photorefractive cubic crystals
which are, in general, optically active. The theory is based on the systematic use of the …

We study the diffraction efficiency of volume phase gratings in Bi 12 GeO 20, when the
grating vector, lying on a (111) plane, is at an angle with respect to the crystallographic …

Analysis of two-wave coupling in cubic crystal classes 23 and 4¯ 3m is presented for
arbitrary orientation of the grating vector and the applied electric field. We show that the most …

Theoretical and experimental investigations of the linear and nonlinear space–charge field
effects in photorefractive materials are reviewed. In particular, the aim is to explore the …

We present a theory of resonant photorefractive wave coupling in cubic photorefractive
crystals that are in general optically active. This theory includes the resonance enhancement …

Abstract The incoherent interaction of (1+ 1)-dimensional Gaussian beams in cubic
