Abstract: Solid glass articles are made by the flame hydrolysis technique. A thin stratum of low viscosity glass soot is applied to the surface of a mandrel. First and second coatings of glass soot are deposited on the surface of the thin stratum to form a porous preform. The refractive index of the soot particles of the first coating is greater than that of the soot of the second coating, and the soot of the first coating has a viscosity lower than that of the second coating. The mandrel is removed, and the soot preform is subjected to a high temperature whereby it is consolidated to form a dense glass blank. The glass surface tension and the relative viscosities of the inner and outer portions of the preform cause the aperture to close during the consolidation process. The thin stratum, which preferably includes P.sub.2 O.sub.5, smoothes over the damage caused by removing the mandrel and reduces or even eliminates seed formation at the axis of the resultant glass blank. The blank is heated and drawn into an optical fiber.

Abstract: An optical fiber waveguide of the type comprising an outer cladding layer, an axially disposed core of SiO.sub.2 doped with GeO.sub.2 and a first inner cladding layer of SiO.sub.2 doped with an oxide such as P.sub.2 O.sub.5 for lowering the preform processing temperature. A second inner cladding layer of pure SiO.sub.2 is disposed between the first inner cladding layer and the core to prevent P.sub.2 O.sub.5 from diffusing into the core, thereby eliminating absorption losses from the P--O--H band in the 1.1-1.8 .mu.m region.

Abstract: A process for producing an optical transmission fiber is provided which comprises feeding highly pure halides, hydrides or organic compounds of Si and B by way of carrier gas on the outer surface of a fused silica rod or a fused silica pipe, or inner surface of a fused silica pipe, oxidizing them and depositing the products to form a pure fused silica layer or a doped fused silica layer containing B.sub.2 O.sub.3, melting the pipe and the deposited layer followed by a spinning. The SiO.sub.2 layer can alternatively contain fluorine instead of B.sub.2 O.sub.3. A further SiO.sub.2 layer can be deposited thereon to improve the spinning processability and lower the index of refraction of the B.sub.2 O.sub.3 containing layer.

Abstract: The invention provides a method for preparing a preform for producing by drawing an optical waveguide comprising a core region and a sheath region whose refractive index varies in the radial direction, so that the index of the former is greater than those of the second. The method consists in starting from a bar of a first composition for forming the core region and in forming, by means of a plasma torch, on its surface, a deposit of a plurality of layers whose composition varies in the radial direction, is characterized in that glass powder is fed to said torch transversely to the jet of said torch; in that said bar is drawn after each layer is deposited to bring its diameter to a value close or equal to the initial diameter; and in that the chemical composition of the glass powder is changed after each layer is deposited. The preform obtained by the present method makes it possible to produce by drawing optical waveguides for applications in the field of information transmission.

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.
