  • Patent number: 6660672
    Abstract: There is provided alkaloid halogen-doped sulfide glasses for an optical amplifier and a fabricating method thereof. An alkaloid halogen-doped sulfide glass is formed of silica doped with a Ge—Ga—S three-component system, Pr3+, and an alkaloid halogen. To fabricate the alkaloid halogen-doped sulfide glass for an optical amplifier, silica doped with Ge, Ga, S, Pr3+, and an alkaloid halogen as a starting material is filled into a container. The container is sealed in a vacuum and the starting material in the container is fused by heating the container. The container is cooled and the starting material is sintered by heating the container at a glass transition temperature.

  • Patent number: 6480663
    Abstract: An optical fiber for an optical amplifier, which contains dysprosium ion (Dy3+) with an improved light amplification efficiency at the 1.31 &mgr;m band. The optical fiber includes a germanium-gallium-sulfide (Ge—Ga—S) glass, an alkali metal halide, and Dy as a rare earth element. In the optical fiber, the interaction of electrons of Dy3+ and phonons in the glass lattice can be minimized, so that the multiphonon relaxation of Dy3+0 from 4F11/2 and 6H9/2 to 6H11/2 is slowed down, and thus the fluorescence lifetime at 1.31 &mgr;m is elongated, further improving the fluorescence efficiency of the optical fiber.

  • Patent number: 6347177
    Abstract: An optical fiber used for an optical amplifier, is formed by doping glass with rare-earth ions. Both praseodymium ions (Pr+3) and erbium ions (Er+3) are used as the rare-earth ions, and the glass is a fluoride glass or a sulfide glass. The optical fiber can be used at wavelengths of both 1.3 &mgr;m and 1.55 &mgr;m. The light amplification efficiency of an optical amplifier made of the optical fiber can be improved compared to that of an optical amplifier formed of only Pr+3 or only Er+3.

  • Patent number: 6272277
    Abstract: An optical fiber for use in a light amplifier. The optical fiber is formed by doping a gerrnanium-gallium-sulfur (Ge—Ga—S) glass containing less sulfur than a GeS2—Ga2S3 stoichiometric composition line with a rare earth element, and further contains 0.1˜10 atomic % of a halogen element base on the Ge—Ga—S glass. By using optical fiber, clustering of praseodymium (Pr+3) ions can be suppressed even when the concentration of added Pr+3 is high, thereby improving light amplification efficiency.
