Abstract
The rigorous coupled-wave model is used to determine the polarization of diffracted waves from two superimposed volume gratings with their grating vectors in the same plane. The phase relations used in computing the phase shift of diffracted beams are derived. The relative phase difference between orthogonal components of the + 1 diffracted order is computed for a single grating and two superimposed gratings. The level of induced ellipticity in polarization is greater for light diffracted from a multiplexed grating than from a single grating. Experimental and theoretical results show that the phase shift of a beam diffracted from two superimposed gratings has both positive and negative values.
