    Abstract: A process is disclosed for making an optical fiber having a graded index glass core enveloped by a cladding material. The ingredients from which the peripheral part of the core glass is to be formed are placed in a closed tube of the cladding material which is more refractory than the core glass. The ingredients are melted to form a glassy liquid which is fined within the tube and then coated (for example, by rotational casting) on the inner surface of the tube. Additional ingredients, from which the inner part of the core glass is to be formed, are then placed in the coated tube, melted and similarly coated on the inner surface of the tube. In this way successive core glass layers, each having a different index of refraction, may be formed within the tube of cladding material. The temperature is then elevated further and the tube and glassy liquid drawn into a fiber.

    Abstract: A METHOD OF FORMING AN OPTICAL WAVEGUIDE BY FORMING A FIRST COATING OF GLASS HAVING A PREDETERMINED INDEX OF REFRACTION ON THE OUTSIDE PERIPHERAL WALL SURFACE OF A SUBSTANTIALLY CYLINDRICAL STARTER ROD OR MEMBER. THEREAFTER, A SECOND COATING OF GLASS IS APPLIED TO THE PERIPHERAL OUTSIDE SURFACE OF THE FIRST COATING, SAID SECOND COATING HAVING A PRESELECTED INDEX OF REFRACTION LESS THAN THE INDEX OF REFRACTION OF THE FIRST COATING. THE STARTER ROD OR MEMBER IS REMOVED FROM THE ASSEMBLY FOLLOWING THE APPLICATION OF EITHER THE FIRST OR SECOND COATING. THE RESULTING SUBSTANTIALLY CYLINDRICAL HOLLOW ASSEMBLY IS HEATED AND DRAWN TO REDUCE THE CROSS-SECTIONAL AREA AND TO COLLAPSE THE FIRST AND INNER COATING OF GLASS TO FORM A FIBER HAVING A SOLID CROSSSECTIONAL AREA. THE COLLAPSED FIRST AND INNER COATING FORMS THE FIBER CORE AND THE SECOND COATING FORMS THE CLADDING FOR THE FIBER.

    Abstract: Optical transmission lines suitable for transmitting electromagnetic radiation within the visible spectrum and adjoining portions of the infrared and ultraviolet spectra consists of a pure amorphous silica core clad by a B2O3-modified silica cladding. The cladding may manifest a substantial uniform refractive index of a value at least 0.1 percent less than that of the core or may be graded to such a lowered value.

    Abstract: A method for producing a solid body of glass is described. The method comprises providing a polymerisable composition, curing the polymerisable composition to obtain a cured body, subjecting the cured body to thermal debinding to substantially remove the organic components in the cured body, and subjecting the cured body to sintering to obtain a solid body of silica glass. The polymerisable composition one or more at least partially organic polymerisable compound(s) which form a liquid composition at operating temperature and a solid source of silica as colloidal silica particles or silica glass micro-/nanoparticles dispersed in the liquid composition. The one or more at least partially organic polymerisable compounds comprises at least one organosilicon compound as a second source of silica that is liquid or solubilisable in the liquid composition at operating temperature to thereby increase the silica loading of the cured body prior to sintering. Compositions and methods for producing solid glass objects by additive manufacturing are also described.
