Research of light diffraction on electrically controlled multilayer inhomogeneous holographic ppm-lc diffraction structures
This article presents an analytical model of light diffraction on electrically controlled multilayer inhomogeneous holographic diffraction structures formed in photopolymer composite materials with nematic liquid crystals having smooth optical inhomogeneity in the thickness of the gratings. Using numerical modeling, it was shown that with an external electrical effect on diffraction layers having a smooth optical inhomogeneity in the depth of the gratings, the angular selectivity of the light beam diffracted in the first order can not only transform, but also have a significant displacement. This effect can be used for possible control of channel rearrangement if such structures are considered as elements of spectral filters.
