Abstract

This paper presents the methods developed to create volume diffraction structures based on nematic liquid crystals (LCs) doped by a polymethine dye and also thin phase gratings formed in LC using the aligning photopolymer. The efficiency of the electric control method for diffraction LC structures is demonstrated and the characteristics of these structures are studied.
