Diffraction Characteristics of Multiplexed Multilayer Inhomogeneous Holographic Diffraction Structures in Photopolymerizing Compositions with Liquid Crystals

We presented the diffraction characteristics of electrically controlled multiplexed multilayer inhomogeneous holographic diffraction structures formed in photopolymerizing compositions with a high proportion of nematic liquid crystals obtained by numerical simulation according to the developed mathematical model. The results obtained demonstrate the possibility of using such structures as spectral DWDM filters, for which a multiple increase in the width of angular selectivity and spectral bandwidth is possible due to the sequential recording of several gratings compared with conventional multilayer diffraction structures. In addition, the possibility of controlling the channel rearrangement by external electrical action on the diffraction layers was also demonstrated.
