Vernadsky University popup.description2 First developed the theory of the Bragg resonance is not the energy exchange core and cladding modes with opposite signs of the topological charge and the circular polarization and the maps of forbidden spectral bands for the following types of chiral crystal optical fiber: a) elliptical core of the structure twisted around the fiber axis. b) a circular core with linear material anisotropy (optical axis oriented perpendicular to the axis chiral crystal optical fiber) in the structure twisted around the fiber axis. c) a circular core in the structure of the double helix. d) a circular structure in the core of multiple double helix fibers. All fibers have a number of shells. Theoretically and experimentally investigated the distribution of singular beams in anisotropic crystals with optical activity, as well as in optical fibers based on them, and conditions for the transfer of the singular mode beam. The conditions for suppression of higher-order modes in chiral crystal optical fiber. The basic requirements for giroanizotropnym guiding structures, conveying the singular beams.
