Abstract: An optical coupler adapted to feed a plurality of optical fibers with light radiation coming from a single fiber or, conversely, to transmit to a single fiber the radiation coming from a plurality of fibers. A round paraboloid receives the optical beams condensed by hemispherical lenses placed in front of the fiber end faces and concentrates them on the end face of the output fiber through a hemispherical lens.

Abstract: In order to improve the transmission characteristics of optical fibers drawn from the preforms manufactured by vapor deposition of silica on an inner wall surface of a supporting tube of glass, the tube is subjected to a two-stage heat treatment with deuterium whereby OH.sup.- groups at least on the inner tube surface are isotopically replaced by OD.sup.- groups. This pretreatment can be carried out in the same apparatus which is subsequently used for producing the preform.

Abstract: A method of making optical performs from which optical fibers are drawn after collapsing of the preform, which comprises depositing by a vapor-phase reaction a plurality of layers on the inner surface of a support tube and controlling the temperature profile around the perimeter of the support so that the thickness of the deposit varies between at least one maximum and at least one minimum. Upon collapse of the support this gives rise to a core having a noncircular cross section.

Abstract: In order to obtain substances that are optically transparent in the infrared range, usable in the manufacture of optical fibers or radiation emitters, a metal or metalloid chalcogenide other than an oxide is produced by a double-substitution reaction between a starting chalcogen compound--particularly a hydride such as H.sub.2 S, H.sub.2 Se or H.sub.2 Te--and a salt of the desired metal or metalloid, e.g. a chloride. The starting compound and the reactant salt preferably are vaporized at a temperature below the melting point of the resulting metal chalcogenide which thereupon precipitates in the reaction chamber.

Abstract: Vapor deposition of doped silica in a reaction chamber on a rotating supporting surface, in the manufacture of a preform for the drawing of an optical fiber, is accompanied by the continuous admixture of deuterium with a flow of carrier gas, specifically oxygen, by which the reactants are transported to the reaction chamber. An isotopic substitution of deuterium for the hydrogen of hydroxyl groups in the reaction products shifts the major absorption peaks to wavelengths outside the minimum-attenuation range of 0.7 to 1.6.mu. used for fiber-optical signaling. The proper ratio of deuterium to carrier gas is maintained with the aid of a mixer having two compartments separated by a perforated diaphragm or a thin metallic foil, one compartment being connected to a deuterium tank while the other communicates with a conduit through which the vapors entrained by the carrier gas pass to the reaction chamber.
