  • Glass compositions
    Patent number: 5772915
    Abstract: A halide glass composition contains iodide and/or bromide. In addition the halide content preferably includes chloride. The preferred metal composition includes no aluminium and 1-10 mole % of (In+Y). These compositions are used as hosts for rare earth lasing dopants, e.g, Pr.sup.3+.
    Type: Grant
    Filed: March 20, 1997
    Date of Patent: June 30, 1998
    Assignee: British Telecommunications public limited company
    Inventors: Animesh Jha, Wayne G. Jordan
  • Halide glass compositions and optical circuits and methods employing same
    Patent number: 5560868
    Abstract: Halide glasses having particular utility as hosts for praseodynmium in order to provide optical amplification by laser activity have a halide content provided as a small proportion, e.g., 1-10 percent, of choride with the remainder as fluoride. The metal content is similar to conventional ZBLAN glasses. The replacement of A1 by Y and In and/or the partial replacement of Na by Cs has synergistic benefits. PR.sup.3+ constitutes a good lasing species for amplifying telecommunication signals at 1300 nm using pumped radiation at 1020 nm.
