Abstract: A hollow optical fiber 10 has an intermediate dielectric layer 12 interposed between an inner periphery side dielectric layer 11 facing a hollow core portion 10a and a metal layer 13. The inner periphery side dielectric layer 11 is formed of calcium fluoride. The intermediate dielectric layer 12 is formed of yttrium fluoride. Metal of the metal layer 13 can be prevented from dispersing into the dielectric layers 12, 11 by the intermediate dielectric layer 12 formed of yttrium fluoride. The hollow optical fiber 10 is manufactured by vapor depositing calcium fluoride on an outer peripheral surface of an acid-soluble glass tube 20 (base material), then vapor depositing yttrium fluoride on its outer peripheral surface, then vapor depositing a metal layer formed of silver, gold or the like on its outer peripheral surface, and thereafter, dissolving the glass tube 20 with acid.

Abstract: A method of making core holes in cast cladding glass for fabricating optical fiber preforms to make single and multimode optical fibers. Liquid cladding glass is pored into a casting mold having a metallic wire that is translated through the liquid glass as it cools so that the wire essentially carves out a smooth cylindrical core hole along the cylindrical axis of the cooled cladding glass. The method substantially reduces surface contamination at the interface of the core hole and the cladding glass because any liquid glass that comes in contacts with the metallic wire is removed during the process, leaving behind a pristine glass surface.

Abstract: Fluoride glass optical fibers are fabricated by minimizing the number of high-temperature operations. A tube comprising an external layer of a first fluoride glass of composition suitable to form the cladding of the fiber and an internal layer of a second fluoride glass of composition suitable to form the core of the fiber is prepared by a conventional rotational casting technique. Then, the internal layer is thinned by means of chemical etching at ambient temperature until the attainment of a ratio between the volumes of the two layers that corresponds to the ratio between the core and cladding diameters required for a single mode fiber, and the resulting tube is drawn.
