  • Patent number: 7676130
    Abstract: The invention includes a composition for an optical fiber coating. An inventive composition includes a non-thiol functional adhesion promoter and less than about 0.5 pph of a strength additive containing a thiol functional group. The invention further includes an optical fiber coated with the inventive composition. A second inventive composition includes a photo-polymerizable composition which contains an adhesion promoter and a non-silicon containing strength additive containing at least about one thiol functional group. A third inventive composition includes a photo-polymerizable composition which has a silane containing adhesion promoter and a strength additive containing at least about one halide functional group. The invention also includes an optical fiber coated with the inventive coating and methods of making an optical fiber including the inventive coating.

  • Patent number: 6737375
    Abstract: Glass frit compositions, calculated in mole percent on an oxide basis, consisting essentially of 24.5 to 29.0% P2O5; 1.0 to 5.0% B2O3; 1.0 to 2.0% Al2O3; and sufficient amounts of SnO and ZnO (51.5 to 66.5% SnO, and 5.0-12.0% ZnO), wherein the molar ratio of SnO:ZnO is in the range of about 5.0:1 to 12:1, and 0.0 to 2.0% SiO2. The glass compositions exhibit, under NMR spectroscopic analysis of 11B nuclei, a signal containing at least two peaks at a chemical shift in the range of approximately −18 to −25 ppm. The frit compositions exhibit long term stability, durability, and resistance to attack against moisture in high temperature and humidity conditions and are capable of attaching optical fiber Bragg gratings without the use of a hermetic chamber and the like. An optoelectronic device that employs a sealing material that comprises a frit made from the glass compositions.

  • Patent number: 6656859
    Abstract: A family of tellurite glasses and optical components for telecommunication systems, the glasses consisting essentially of, as calculated in cation percent, 65-97% TeO2, and at least one additional oxide of an element having a valence greater than two and selected from the group consisting of Ta, Nb, W, Ti, La, Zr, Hf, Y, Gd, Lu, Sc, Al and Ga, that may contain a lanthanide oxide as a dopant, in particular erbium oxide, and that, when so doped, is characterized by a fluorescent emission spectrum having a relatively broad FWHM value.
