The diffraction characteristics of multiplexed holographic gratings are investigated using a rigorous coupled-wave approach. The effect of the angular separation between the multiplexed holograms on the diffraction efficiency, the direct cross-talk, and the indirect cross-coupling between the two holograms is determined. It is shown that the indirect cross-coupling could cause serious limitations on the maximum diffraction efficiency of the multiplexed holograms and on the total number of holograms that can be multiplexed.
