HOTOREFRACTIVE COMPOSITES BASED ON ACRYLATE AND STYRENE TYPES OF TRIPHENYLAMINE POLYMER

Abstract

Two types of photorefractive (PR) composite based on acrylate and styrene type of triphenylamine polymer were fabricated. The PR performance was evaluated through diffraction efficiency, response and decaying time. These parameters could be obtained by applying degenerated four waves mixing method. The composite based on styrene type had faster response and decaying time while diffraction efficiency was only 16 %. The composite using acrylate type had slightly slow response results. However, the diffraction efficiency could reach 30 % and shelf-life was significantly improved.
