    Abstract: A low loss cladded halide fiber for transmission of infrared energy is provided, and a process for making the same by growing a single crystal ingot from a powder of a core halide, extruding or machining the ingot to provide a cylindrical billet core, assembling the billet core, preferably wrapped in a polymer film, within a sleeve member of a second halide of lower refractive index than the core, prepared in the same fashion as the core, and coaxially core drilled to accept the billet core. The assembled composite billet is covered with a polymer film, heated, and extruded to form a polymer coated fiber having a diameter in the range of 75 to 2,000 microns. The extruded fiber may be rapidly cooled as it leaves the extrusion die to minimize grain size and scattering loss and may be contained in a coaxial outer strength member.

    Abstract: A glass optical waveguide preform is formed by chemical reaction of gaseous and/or vaporized ingredients within a glass substrate tube. A reactant feed tube extends into a first end of the substrate tube. One of the reactants flows through the feed tube, and another flows through the annular channel between the feed and substrate tubes. The reactants combine just downstream of the end of the feed tube and react to form particulate material, at least a portion of which deposit in the substrate tube. The output end of the feed tube traverses the substrate tube so that the region of maximum soot deposition moves along the length of the substrate tube. A hot zone traverses the substrate tube in synchronism with the feed tube to sinter the deposited soot.

    Abstract: PURPOSE:To obtain an optical fiber capable of transmitting light having wavelengths in a region ranging from the near ultraviolet region to the intermediate infrared region with small loss, by sticking a molten mixture of cesium bromide with cesium iodide to the outside of a core fiber of cesium iodide and by solidifying the mixture. CONSTITUTION:A core fiber 4 of cesium iodide is manufactured by the stepanov method or other method. A molten mixture 2 consisting of 2-57mol% cesium bromide and the balance cesium iodide is prepared and charged into a crucible 1. The mixture 2 is allowed to flow out from a circular slit 3 positioned at the tip of the crucible 1 in contact with the fiber 4 at a prescribed flow rate, and the mixture 2 is stuck to the outside of the fiber 4 while drawing the fiber 4 downward with rollers 5 at a prescribed rate. The coat of the stuck mixture is solidified by cooling with water-cooled pipes 6 to form a clad. Thus, the desired optical fiber is obtd.

    Abstract: A known method for producing synthetic quartz glass comprises: (a) reacting a carbonic silicon compound-containing raw material with oxygen in a reaction zone into SiO2 particles, (b) precipitating the SiO2 particles on a sedimentation area by forming a porous SiO2 soot body containing hydrogen and hydroxyl groups, (c) drying the porous SiO2 soot body, and (d) glazing to the synthetic quartz glass by heating the soot body up to a glazing temperature. In order to facilitate cost-efficient production of quartz glass by means of pyrolysing or hydrolysing a carbon-containing silicon compound using a carbon-containing raw material, the invention describes the production of a soot body with a carbon content within the range of 1 ppm by weight to 50 ppm by weight.
