The diffraction gratings in novel photopolymer were fabricated by optical interference method. Holographic recording in new polymer layers can be applied for optical information storage. The hydrophilic and hydrophobic polymers are used with the monomer of acrylamide, which are well miscible with the sensitizing dye of yellow eosin and the charge transfer agent of triethanolamine. Addition of the crosslinking agent bisacrylamide stabilizes the formed structures against thermal and environmental relaxations. We compared the diffraction efficiencies of new polymer samples with that of the conventional photopolymer. Relatively high diffraction efficiency can be obtained from LPOMPP-02 series. The influence of the UV curing on the diffraction grating is also studied when the diffraction efficiency becomes stable. The diffraction efficiency under UV irradiation shows slight decrement and becomes stable at a lower value. The surface topographical change of the photopolymer layer was observed after irradiation of the two polarized lights. The actual periodicity of the surface relief grating is about 1.95-1.98 μm according to the AFM profiles close to the theoretical value of 1.92 μm.
