Abstract: A method of forming an alkali metal oxide-doped optical fiber by diffusing an alkali metal into a surface of a glass article is disclosed. The silica glass article may be in the form of a tube or a rod, or a collection of tubes or rods. The silica glass article containing the alkali metal, and impurities that may have been unintentionally diffused into the glass article, is etched to a depth sufficient to remove the impurities. The silica glass article may be further processed to form a complete optical fiber preform. The preform, when drawn into an optical fiber, exhibits a low attenuation.

Abstract: A method for deposition glass soot for making an optical fiber preform. A fuel and a glass precursor are flowed to a burner flame forming glass soot which is deposited onto a glass target. By first depositing an insulating layer of glass soot with a low velocity burner flame, the amount of water which may be adsorbed into the surface of the glass target can be reduced. Thereafter, the flame velocity may be increased to increase the deposition rate of the glass soot without significantly increasing the concentration of water incorporated into the glass target.

Abstract: It is an object of the present invention to provide a light emitting device of the next generation optical device having a broad emission property that a width at half maximum of an emission spectrum is large in a wavelength range of visible light and capable of recognizing white light emitting by photoluminescence (PL). In a baking process for baking a pressure molding formed by pressure molding of silica fine particles such as fumed silica, a baking temperature is made as not more than 1000° C., hydroxyl groups of the silica fine particles are sufficiently subjected to dehydration condensation reaction so that the particles becomes transparent, a structural defect generated in the process is held without being relaxed, and thus a silica glass is generated. The silica glass is employed as a fluorescent substance.

Abstract: Disclosed are high purity synthetic silica glass material having a high OH concentration homogeneity in a plane perpendicular to the optical axis, and process of making the same. The glass has high refractive index homogeneity. The glass can have high internal transmission of at least 99.65%/cm at 193 nm. The process does not require a post-sintering homogenization step. The controlling factors for high compositional homogeneity, thus high refractive index homogeneity, include high initial local soot density uniformity in the soot preform and slow sintering, notably isothermal treatment during consolidation.
