  • Non-linear opticaly active molecules, their synthesis, and use
    Publication number: 20120059163
    Abstract: In one aspect, the present invention provides a hyperpolarizable organic chromophore. The chromophore is a nonlinear optically active compound that includes a ?-donor conjugated to a ?-acceptor through a ?-electron conjugated bridge. In other aspects of the invention, donor structures and acceptor structures are provided. In another aspect of the invention, a chromophore-containing polymer is provided. In one embodiment, the chromophore is physically incorporated into the polymer to provide a composite. In another embodiment, the chromophore is covalently bonded to the polymer, either as a side chain polymer or through crosslinking into the polymer. In other aspects, the present invention also provides a method for making the chromophore, a method for making the chromophore-containing polymer, and methods for using the chromophore and chromophore-containing polymer.

  • 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.
