Abstract: The method and apparatus for producing liquid silicon of high purity and for casting silicon. Hydrogen and a hydrogenated silane in gaseous state are mixed, preferably with a source of a small amount of oxygen, in a heated chamber producing the liquid silicon, with the exhaust gases bubbling out of the melt under a baffle. The chamber for the melt of liquid silicon preferably is lined with silicon dioxide. The liquid silicon may be used in making high purity vitreous silica and may be used in making castings of silicon. In making castings, the liquid silicon is accumulated in a second chamber and is periodically drawn from the second chamber into a third chamber which contains the mold for the casting.

Abstract: A method is provided for producing high purity oxide products of phosphorus and silicon such as, for example, a P2O5 and SiO2 glass wherein a silicon alkoxide is directly reacted with phosphorous acid, phosphoric acid, phosphorus pentoxide, or mixtures thereof, in the absence of any addition of a separate hydrolysis catalyst to produce a single phase solution reaction product and this reaction product with water is converted to a two-phase system, which two-phase system is removed of its free liquid components and the residue is then thermally decomposed to produce a product of phosphorus and silicon. This oxide product may be converted to a substantially unitary shape by conventional melting techniques or by conventional sintering techniques. The product may be used as an additive in conventional glass melting operations to supply at least a portion, and preferably all, of the P2O5 and/or silica requirements of the batch or the product may be compacted and suitably fired into a substantially unitary body, which body is an excellent target in sputtering applications for forming films on semiconductive materials such as, for example, silicon chips.

Abstract: An optical fiber has a core region that is doped with one or more viscosity-reducing dopants in respective amounts that are configured, such that, in a Raman spectrum with a frequency shift of approximately 600 cm−, the fiber has a nanoscale structure having an integrated D2 line defect intensity of less than 0.025. Alternatively, the core region is doped with one or more viscosity-reducing dopants in respective amounts that are configured such that the fiber has a residual axial compressive stress with a stress magnitude of more than 20 MPa and a stress radial extent between 2 and 7 times the core radius.According to another aspect of the invention a majority of the optical propagation through the fiber is supported by an identified group of fiber regions comprising the core region and one or more adjacent cladding regions. The fiber regions are doped with one or more viscosity-reducing dopants in respective amounts and radial positions that are configured to achieve viscosity matching among the fiber regions in the identified group.

Abstract: Various embodiments described herein include rare earth doped glass compositions that may be used in optical fiber and rods having large core sizes. Such optical fibers and rods may be employed in fiber lasers and amplifiers. The index of refraction of the glass may be substantially uniform and may be close to that of silica in some embodiments. Possible advantages to such features include reduction of formation of additional waveguides within the core, which becomes increasingly a problem with larger core sizes.
