    Abstract: This disclosure is directed to a silica-titania-niobia glass and to a method for making the glass. The composition of the silica-titania-niobia (SiO 2 -TiO 2 -Nb 2 O 5 ) glass, determined as the oxides, is Nb 2 O 5 in an amount in the range of 0.005 wt.% to 1.2 wt.% TiO 2 , in an amount in the range of 5 wt.% to 10 wt.%, and the remainder of glass is SiO 2 . In the method, the STN glass precursor is consolidated into a glass by heating to a temperature of 1600°C to 1700°C in flowing helium for 6 hours to 10 hours. When this temperature is reached, the helium flow can be replaced by argon for the remainder of the time. Subsequently the glass is cooled to approximately 1050°C, and then from 1050°C to 700°C followed by turning off the furnace and cooling the glass to room temperature at the natural cooling rate of the furnace.

    Abstract: A method for making a glass ceramic, optoelectronic material such as a clad optical fiber or other component for use in an optoelectronic device. The method comprises preparing a glass composition batch to yield a precursor glass for a nanocrystalline glass-ceramic that is doped with at least one kind of optically active ion, such as a transition metal or lanthanide element; melting the batch; forming a glass cane; surrounding the cane with a chemically inert cladding material shaped in the form of a tube; drawing a glass fiber from the combined precursor-glass "cane-in-tube" at a temperature slightly above the liquidus of the precursor glass composition, and heat treating at least a portion of the drawn clad glass fiber under conditions to develop nanocrystals within the core composition and thereby forming a glass ceramic.

    Abstract: The present invention is directed to methods of producing soot used in the manufacture of optical waveguides. Both non-aqueous liquid reactants and aqueous solutions containing one or more salts are delivered through an atomizing burner assembly to form a homogenous soot stream containing the oxides of the selected elements contained within the non-aqueous liquid reactant and the aqueous solution. The resulting multi-component soot is collected by conventional methods to form preforms used in the manufacture of optical waveguide fibers. Alternatively, an aqueous solution may be atomized with a gas at a first burner assembly to form an aerosol and a reactant vaporized for delivery to a second burner assembly. Preforms produced by the methods are also disclosed. The aqueous solution is preferably one comprising a metal salt, e.g. acetate, nitrate, sulfate, carbonate, chloride, hydroxide. The metal of the metal salt is preferably an alkali metal, an alkaline earth metal, lead, lanthanum, cobalt, antimony, erbium, aluminum, neodymium, praeseodymium.
