摘要:
This invention relates to a nonlinear optical dye, a photorefractive composite including the same, and a photorefractive device. The purpose is to provide a nonlinear optical dye, a photorefractive composite including the same, and a photorefractive device with improved response speed to the applied electric field by controlling the molecular structure. The nonlinear optical dye according to the present invention has alkyl or alkoxy groups with carbon numbers of 1 to 10.
