摘要： A particle having a magnesium aluminate core and a fluoride salt coating on the core. The particle has been heated in an oxidizing atmosphere to a temperature in the range of about 400° C. to about 750° C. A method of making a particle by mixing a magnesium aluminate core with a solution of a fluoride salt in a solvent to form a slurry and spraying the slurry into a drying column. The slurry enters the column as an aerosol under thermal conditions that avoid boiling the solvent. The thermal conditions in the column evaporate the solvent as the aerosol moves through the column to form a coating of the fluoride salt on the core while substantially avoiding spalling.

摘要： A core/clad glass optical fiber is made by melting a core glass rod and a adding glass rod in separate crucibles which are not intersecting with respect to each other and the respective core and cladding glass melts passed out of contact with each other to a glass melt contacting zone proximate a fiber drawing orifice in which the cladding glass surrounds the core glass and a core/clad glass fiber is drawn. This process enables the clad glass fiber to be drawn directly from core and cladding glass rods without the need for a preform or forming a melt from glass chards or chunks, thereby reducing the cost of producing the fiber and also producing a glass clad optical fiber of high purity and excellent concentricity. Chalcogenide glass fibers having a concentricity of 100% have been made.

摘要： An optical fiber termination connector includes an elongated structure with chamber extending therethrough open at both ends, a fiber disposed in the chamber and spaced therefrom, a solid first material disposed in the chamber around the fiber, and an air gap in the chamber around the end of the fiber. The process includes the steps of locating a fiber in a chamber disposed vertically, with the end of the fiber extending beyond the lower portion of chamber; dipping a lower portion of the chamber into a first material in liquid form so that the first material enters the lower portion of the chamber to a level below an exit port located in the lower portion of the chamber; solidifying the first material disposed in and around the chamber and the fiber; above the solid first material; polishing the lower end of the fiber until it is flush with the chamber at the lower thereof; and removing the first material to form an air gap between the fiber and the lower portion of the chamber. The air gap is large enough to allow independent thermal expansion of the fiber.
