Abstract

A thick-layer selfdeveloping photosensitive medium – dye-doped jelly-like gelatin was earlier proposed and investigated by us [1,2]. It provides optical recording of the stationary volume phase gratings with high values of diffraction efficiency and angular selectivity. For a wide range of scientific and technical applications including holographic data storage, holographic optical elements, photonic crystals etc. multiplexed volume holograms are required. In this work an angular multiplexing of the volume phase Bragg gratings in dye-doped jelly-like gelatin is reported.
