Abstract
The application of dichromated gelatine transmission holograms as holo graphic optical elements for permutation components is demonstrated. T hese holographic deflection elements will be used as permutation compo nents in a demonstrator for an optoelectronic switching network workin g with 1 GHz per channel. The use of a standard holographic material a nd recording process for faceted holograms for infrared light at 1.5 m u m is investigated. The important parameters such as refractive index modulation of the gelatine, angular selectivity and scattering are in vestigated and compared with the corresponding results for visible lig ht. It is shown that it is possible to produce holograms for infrared light with similar diffraction efficiencies to those for visible light .
