Abstract

Liquid crystal circular core optical fibers cannot have a stable structure of arrangement because of misfit of core geometry and properties of liquid crystals. Fibers of high ellipticity of core are much better in this case but controlling the state and degree of arrangement of a liquid crystal by external electric field requires application of high voltage. The work presents the technology of substrate of liquid crystal core fibers in the form of quartz glass capillaries with highly elliptic central hole and two additional holes placed at both sides of the central one along the fiber. On the surface of side holes layers of nickel were deposited by thermal decomposition of nickel carbonyl from a gaseous phase. Substrates 2 m long with dimensions of central hole 4 x 18 μm were obtained and characterized. The produced substrates may allow preparation of a new generation of liquid crystal core fibers. The work also presents the design of laboratory scale apparatus for preparation of a new generation of liquid crystal core fibers. The work also presents the design of laboratory scale apparatus for preparation of nickel carbonyl as well as conditions of its synthesis.
