Abstract: PURPOSE: An oxide structure usable for an optical waveguide and a method of forming the oxide structure are provided to produce a plurality of substrates coated with oxide film in a short time. CONSTITUTION: Gaseous reactants are introduced into each of the chambers(20,30,40) through gas lines. Once reactants have been introduced in a chamber, a chemical reaction is proceeded and the product of that reaction forms a layer or film of material on the exposed surface of the substrate that is moving through the chamber on a conveyor belt(50). In order to isolate the chambers(20,30,40) from each other and to allow for separate chemical reactions to occur in each of the chambers(20,30,40), sets of curtains(70) are preferably positioned between the chambers(20,30,40) and inert gas lines(80) pump inert gas between the chambers(20,30,40). The inert gas typically flows through the curtains(70) and into one of the chambers(20,30,40), thereby forcing all of the gaseous reactants to remain in the chambers into which the gaseous reactants were introduced.

Abstract: The manufacture of glass films on substrates involves the flame reaction of an aerosol comprised of droplets of a solution containing all the precursors for the glass. A solution containing the precursors for all oxide components is atomized, and the resulting droplets are reacted in a flame to form spherical glass particles which are deposited on a heated substrate. By moving the substrate through the flame, a homogeneous deposit is achieved. Subsequent heat treatment in a furnace sinters the porous particle layer into a clear glass. The method has been successfully employed for the formation of sodium borosilicate glass films on silicon substrates and rare earth-doped multicomponent glass films for active devices.

Abstract: A doped silica-titania (“DST”) glass article that includes a glass article having a glass composition comprising a silica-titania base glass containing titania at 7 to 14 wt. % and a balance of silica, and a dopant selected from the group consisting of (a) F at 0.7 to 1.5 wt. %, (b) B2O3 at 1.5 to 5 wt. %, (c) OH at 1000 to 3000 ppm, and (d) B2O3 at 0.5 to 2.5 wt. % and OH at 100 to 1400 ppm. The glass article has an expansivity slope of less than about 1.3 ppb/K2 at 20° C. For DST glass articles doped with F or B2O3, the OH level can be held to less than 10 ppm, or less than 100 ppm, respectively. In many aspects, the DST glass articles are substantially free of titania in crystalline form.
