OPTICAL INFORMATION TECHNOLOGIES, ELEMENTS, AND SYSTEMS: LIQUID CRYSTAL PHOTOPOLYMER COMPOSITE WITH A PERIODIC STRUCTURE

摘要

A composite material with an ordered periodic structure was formed as a result of spatially nonuniform photopolymerization and phase separation of a nematic liquid crystal and a polymer from the initial mixture containing a new acrylate monomer. The structure ensures refractive index modulation in the composite material volume. The obtained composite material is promising for application as electrically switchable transmission gratings.
