  • Publication number: 20070141357
    Abstract: Optical articles, such as displays, optical lenses, windows, optical polarizers and transparent films are made as a composite structure comprising a substrate and an anti-reflective coating applied to the substrate. The anti-reflective coating comprises: A) a fluoroelastomer having cures sites selected from the group consisting of bromine atoms, chlorine atoms, iodine atoms, non-conjugated dienes, and mixtures of two or more thereof; and B) a non-fluorinated multiolefinic cross linking agent. The surface of the substrate may be treated by simultaneously bombarding the surface with an ionized inert gas, and etching the surface with an ionized reactive gas, so as to improve the adhesion of the coating to the substrate.

  • Publication number: 20040037531
    Abstract: A waveguide device having a tailored thermal response includes a solvent-resistant substrate including a surface, the substrate having a thermal coefficient of expansion. The waveguide device further includes a waveguide layer formed on the surface of the substrate. The waveguide layer has a temperature-dependent refractive index characterized by a negative thermo-optical coefficient. The thermal response of the waveguide device includes a temperature-dependent wavelength shift proportional to a thermal response parameter equal to a sum of the thermo-optical coefficient and the product of the refractive index and the thermal coefficient of expansion.
