    Abstract: In accordance with the present invention, there is an optical amplifier fiber comprising a core manufactured from a phosphate glass doped with a rare earth element and a cladding manufactured from a phosphate glass surrounding the core. The core has a radiative lifetime in the range of 7 to 9 milliseconds at 1535 nm, a fluorescence lifetime of greater than 7.5 milliseconds at 1535 nm. The optical amplifier fiber has a diameter ratio in the range of 0.036 to 0.044, a transformation point difference of the core and the cladding, measured in (nullC.), less than 5%. Further, the optical amplifier fiber has a coefficient of thermal expansion, measured in (/nullC.), difference between the core and the cladding is less than 2% and an absorption cross section in the range of 0.60null10null24m2 to 0.72null10null24 m2, in the range of 1530 nm to 1540 nm.

    Abstract: A glass optical waveguide preform is formed by chemical reaction of gaseous and/or vaporized ingredients within a glass substrate tube. A reactant feed tube extends into a first end of the substrate tube. One of the reactants flows through the feed tube, and another flows through the annular channel between the feed and substrate tubes. The reactants combine just downstream of the end of the feed tube and react to form particulate material, at least a portion of which deposit in the substrate tube. The output end of the feed tube traverses the substrate tube so that the region of maximum soot deposition moves along the length of the substrate tube. A hot zone traverses the substrate tube in synchronism with the feed tube to sinter the deposited soot.
