    Abstract: A starting material for producing optical fibers contains metal halides. The refractive index of the optical fiber formed from the starting material is predeterminable by adjusting a partial pressure ratio of a halogen-containing gas mixture. The starting material is produced by mixing halogenated gases into a gas mixture with the desired partial pressure ratio, causing a chemical reaction at a first temperature of the gas mixture with at least metal to form a reaction product, the first temperature being higher than the melting temperature of the reaction product and cooling the reaction product to a second temperature that is below the melting temperature.

    Abstract: A method of making silver halide fibers involves reducing turbulence and friction during extrusion by moving an extrusion die in a direction opposite from flowing fiber and against a stationary preform arrangement. In another embodiment, the preform is doped with AgI or is a metal compound of the formula MY wherein M is selected from Li, Na, K, Rb, Cs; or MY.sub.2 wherein M is selected from Mg, Ca, Sr, Pb, Ba, Cd or Hg, and Y is selected from Cl, Br, or I. The resulting fiber has a more even core/clad interface with decrease in grain size to fiber surface and texture elongated along the fiber axis. This structure together with strengthening and stabilizing dopants, added to fiber material, gives decreased and stabilized optical losses and a higher elasticity of fibers.

    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.
