  • Liquid crystal materials and electrooptic devices with a liquid crystal-containing cladding
    Publication number: 20060182401
    Abstract: Broadly, then, one aspect of the present invention is a functional optical material composed of a liquid crystal (LC) evidencing a pair of refractive indices (RI's) and a polymer in which the LC is dispersed. The refractive index (RI) of said polymer may be outside of the L C RI's by at least about 0.03. Another aspect of the present invention is a functional optical material composed of a liquid crystal (LC) and a polymer in which the LC is dispersed, wherein said LC is less than about 5% miscible in said polymer. A further aspect of the present invention is a functional optical material composed of a liquid crystal (LC) and a polymer in which the LC is dispersed, wherein the cladding contains not more than about 20 wt-% LC. In all of these embodiments, the functional optical material can be clad to an optical waveguide and can optionally contain a chromophore.
