Abstract: Optical fibers doped with nonglass forming refractory oxides, such as alumina and zirconia, are disclosed. Devitrification is retarded by adding an additional glass forming component, such as P.sub.2 O.sub.5, and by rapidly quenching the heated glass. Aluminum and zirconium-containing precursor vapors are formed by passing halide gas over heated aluminum or zirconium wire.

Abstract: Suspensions of particulate oxides, e.g., fumed silica, are prepared in non-aqueous media and the suspensions are used to cast shapes for glass or ceramic products. The suspensions are formed and then caused to gel by means of an added gelling agent, and thereafter dried and, optionally, sintered to transparent glass or void-free ceramic products.

Abstract: A method of making glass optical waveguides by the flame hydrolysis technique. Particles of glass soot produced by flame hydrolysis are deposited on the outside surface of a mandrel to form a porous preform. The soot particles closer to the mandrel have a refractive index greater than that of the soot disposed toward the outer surface of the preform. The mandrel is removed and the resultant hollow soot preform is supported in a draw furnace through which a helium-rich gas flows. The preform is heated to a temperature sufficient to cause said soot to consolidate and simultaneously permit an optical waveguide filament to be drawn therefrom.

Abstract: A method of manufacturing an O-ring type optical waveguide wherein a layer of fused silica is formed on the smooth cylindrical surface of an elongated member of fused silica and thereafter a thin layer of doped fused silica having an index of refraction greater than that of said fused silica is formed over said layer of fused silica. A second layer of fused silica is then formed over the layer of doped fused silica and the composite structure is heated to its drawing temperatures and drawn to reduce the cross sectioned area thereof to form an optical waveguide having a cylindrical layer of higher refractive index interposed between a core and an outer cylindrical layer of lesser refractive index.

Abstract: A method of incorporating an additive or dopant oxide in a glass body produced by the flame hydrolysis technique. Particles of the primary glass former are produced by flame hydrolysis and deposited to form a porous body which is impregnated, in part at least, with a dopant which may be dissolved or suspended in a vehicle. The body is then thermally consolidated with the dopant dispersed therein.

Abstract: A METHOD OF FORMING AN OPTICAL WAVEGUIDE BY FIRST FORMING A COATING OF GLASS ON THE INSIDE WALL OF A GLASS TUBE, THE GLASS TUBE AND THE FIRST COATING BEING OF SUBSTANTIALLY SIMILAR MATERIAL. THEREAFTER, A SECOND COATING OF GLASS IS APPLIED TO THE INSIDE WALL OF THE GLASS TUBE OVER THE FIRST COATING, SAID SECOND COATING HAVING A PRESELECTED DIFFERENT INDEX OF REFRACTION FROM THAT OF THE FIRST COATING. THE GLASS TUBE AND COATING COMBINATION IS THEREAFTER DRAWN TO REDUCE THE CROSS-SECTIONAL AREA AND TO COLLAPSE THE SECOND AND INNER COATING OF GLASS TO FORM A FIBER HAVING A SOLID CROSS-SECTIONAL AREA. THE COLLAPSED INNER COATING FORMS THE FIBER CORE AND THE FIRST COATING FORMS THE CLADDING FOR THE FIBER WHILE THE EXTERIOR GLASS TUBE PROVIDES STRUCTURAL STRENGTH FOR THE FIBER.
