  • Patent number: 7071268
    Abstract: An electro-optic (EO) polymer that has a tunable index of refraction and are synthesized by the copolymerization a bisphenol monomer including a chromophoric structure and two diepoxy monomers. One diepoxy monomer includes at least one fluorine atom, and the second diepoxy monomer includes no fluorine atoms. The EO films are prepared by applying an electric field across the film as the film is heated to its glass transition temperature. The electric field is removed after cooling the film. The index of refraction of these nonlinear optical polymer materials is tuned between about 1.58 to about 1.66 (measured with light having a wavelength of about 1.3 microns).

  • Patent number: 6389215
    Abstract: An optical waveguide subsystem, and process, having at least one cladding in contact with at least one core. The cladding has a refractive index less than the refractive index of the core. Either the cladding or core contains a crosslinked polyimide that is substantially meta-linked. The polyimide has an absolute birefringence of from about 0.01 to about zero.

  • Patent number: 6114031
    Abstract: This invention is comprised of new nonlinear optic polymers and a new Lanir-Blodgett (LB) film deposition scheme for which these polymers were designed. The invention is unique because it produces an electro-optic film which has never undergone electric-field poling nor high temperature treatment. It eliminates the dilution effect of the long hydrophobic alkyl groups, and creates stronger ionic bonds between the polymer chains. Finally, the invention reduces the time to make a film of a given thickness by at least half by virtue of depositing two polymer layers per stroke. The new polymers are comprised of asymmetric chromophores linked head-to-head by alternating two different kinds of bridging groups. One of the bridging groups contains one or more ionic groups, and the other bridging group contains one or more non-ionic, hydrophilic groups.

  • Patent number: 5904990
    Abstract: Until recently, conducting polymers have been used as protective coatings. lthough these types of polymers appear to be effective in most cases, problems have resulted when attempting to bind these polymers to an aluminum surface. The polymers of this invention adhere extremely well to aluminum and aluminum alloys and thus, provide a very effective form of corrosion protection.

  • Patent number: H2046
    Abstract: A process that lends itself to automation for producing multi-layer second-order nonlinear optical polymer (NLOP) thin films by the forming of a polycation layer containing an NLO-active cationic polymer, having non-centrosymmetric chromophores, on a substrate followed by the forming of a polyanion layer, also having non-centrosymmetric chromophores, on the polycation layer. A predetermind number of the polycation and the polyanion layers may be alternated upon the surface as well as one or more buffer layers. An added benefit is the formation of an ultra-smooth surface of the same order of roughness as the substrate upon which the layers are formed.
