Abstract
The recording of the efficient fan-out elements as volume holograms has been studied using coupled wave theory. The authors have found that the efficiency and uniformity of regular fan- out elements depend strongly on the relative phases of the object waves, if the thickness t of the holographic emulsion is smaller than t<(lambda) /(n tan(theta) 0 (Delta) (alpha) ). High efficiency and uniformity can be achieved by optimized phases of the object beams, thereby requiring a low dynamic range of the holographic recording material.
