Study on holographic characteristics in ZnMA doped PQ-PMMA photopolymer

The holographic characteristics in phenanthrenequinone and Zinc methylacrylate doped poly-(methyl methacrylate) photopolymers are experimentally studied. The role of ZnMA molecules which is to accelerate the photochemical reaction in material is confirmed by experiment. The doping of ZnMA component results in a higher diffraction efficiency and photosensitivity than typical phenanthrenequinone doped poly-(methyl methacrylate) system. Moreover, the response region and dynamic range are obviously improved.

► ZnMA doped PQ-PMMA photopolymers are fabricated by optimizing preparation.
► ZnMA as catalyst accelerates grating formation; improves the diffraction efficiency and photosensitivity.
► In multiplexing the response region and dynamic range are improved.
► The influence of ZnMA dopant on long-term stability of gratings is neglectable.
