    Abstract: The present invention provides an optical fiber providing high photosensitivity in the absence of hydrogen loading as well as a low numerical aperture. One aspect of the present invention relates to an optical fiber including a core, the core comprising silica doped with at least about 6 mol% germania and at least about 0.9 wt% fluorine; and a cladding surrounding the core. The optical fiber of the present invention is suitable for the production of fiber Bragg gratings.

    Abstract: The invention reflects discovery of a liquid phase doping technique that, unlike previous techniques, exhibits very little fluorine depletion upon subsequent heating. The invention involves the steps of providing a silica sol comprising a tetraalkylammonium hydroxide and a di-, tri-, or tetraalkylammonium fluoride, the sol having pH of about 10 to about 14, adding a gelling agent to the sol to induce gelation, casting or extruding the sol to form a gel body, and then drying, heat treating, and sintering the body. Advantageously, the fluorine-containing compound is tetramethylammonium fluoride.

    Abstract: PURPOSE: To provide a new method for producing fluorodopant-injected silica glass. CONSTITUTION: This method for producing the product, comprises a step for preparing a silica sol which comprises a tetraalkylammonium hydroxide and a di-, tri- or tetra-alkyl ammonium fluoride and has a pH value of about 10 to about 14, a step for adding a gelling agent to the sol to gel the sol, a step for casting or extruding the gel to form a gel-like article, and a step for drying, thermally treating and calcining the gel-like article. The fluorine-containing compound is preferably tetramethylammonium fluoride. The product obtained by the liquid phase doping method scarcely loses the fluorine, even when the product is subjected to a subsequent heating treatment.
