摘要： A method of producing a device for fixing optical fibers, comprising the steps of disposing a glass shaping pre-form having the shape similar to the shape of a product as viewed on the plane and having the shape which describes the flat surface or an outward curved surface when positioned in a pressing direction at the time of press molding, inside a mold having a cavity of a predetermined shape; and heating the glass shaping pre-form to a moldable temperature so as to form at least one ridge comprising a free surface. This method eliminates the drawbacks of such a device machined in the prior art that the production cost is high and mass-production is difficult.

摘要： A manufacturing method for a glass product not having a rotatively symmetric body like an optical fiber fixing member, but having a fine structure such as that of optical fiber engagement portions, to transfer the fine structure with a high precision without creating molding burrs, includes the steps of placing a glass material in a cavity defined by a lower mold, an upper mold, and a side mold, molding the glass material in the cavity under pressure into the glass product and in so doing controlling that the glass material has a viscosity range of 10 to 10 poises at the beginning of the molding operation under pressure, that the lower mold is at a temperature in a range such that the glass material indicates the above viscosity range, and that the upper and side molds are at a temperature in a range such that a converted viscosity of the glass material at the temperature of the upper and side molds is 5 to 100 times higher than the viscosity of the glass material at the temperature of the lower mold, and decreasing the temperature of the lower mold at the same time that or after the glass product begins to be molded under pressure. To produce an optical fiber fixing member, the lower mold has a mold face for molding optical fiber engagement portions of the optical fiber fixing member; the upper mold has a mold face for molding a bottom of the optical fiber fixing member; and the side mold has a mold face for molding a side face of the optical fiber fixing member.

摘要： An optical fiber fixing member having optical fiber engagement grooves (2) and crests (5) between the engagement grooves (2) is molded as one piece. A mold (21) pressurizes glass preform (G) so that the glass preform (G) will not completely be filled into recessed portions (25) of the mold (21) which has raised portions (26) and recessed portions (25) for transfer-forming the engagement grooves (2) and crests (5). By transferring the shape of the raised portions (26) of the mold (21), the optical fiber engagement grooves (2) are formed, with their surfaces as a mold-transferred surface (6). Because the preform (G) is not filled completely into the recessed portions (26), the crests (5) of the optical fiber fixing member have round free surfaces (7), to which the shape of the recessed bottom portions (25a) of the mold (21) is not transferred. In the optical fiber fixing member molded by using a mold and heating the glass to high temperatures, it is possible to reduce transmission losses due to microcracks in the optical fibers and improve mold release and burr control.

摘要： PROBLEM TO BE SOLVED: To provide a Faraday rotator the light transmittance of which is improved while reducing its manufacturing cost and to provide an optical isolator.
SOLUTION: The Faraday rotator 1 is manufactured by depositing an antireflection film 3 on two surfaces of a substrate 2 such as glass which are opposed to each other in parallel and depositing a magneto-optical film (for example, a Bi-substituted garnet film) 4 on each of the antireflection films 3 by an aerosol deposition method. An optical element for the polarization-dependent optical isolator is manufactured by arranging the Faraday rotator 1 between two sheets of polarizing glass 5 arranged oppositely so that the polarization axis of one of two sheets is deviated from that of the other by around 45°.

摘要： PROBLEM TO BE SOLVED: To enable removal of restriction in size reduction and integration of a device by changing over an optical path in a three-dimensional direction. SOLUTION: An optical inserting and branching device has a first light input part 2 and a first light output part 3 provided on a substrate K, optical wave guides 11, 12 and 13 formed on the substrate so as to output light input from the first light input part from the first light output part, and slits 32 and 33 formed to cross the light guides. In the case that the slits 32 and 33 are filled with matching oil S, light is straightly advanced to cores 11, 12 and 13. In the case that the matching oil is removed from the slits 32 and 33, light passing through the core 11 is bent vertically to the substrate K due to entire reflection action of the slit 32. Light entering the substrate K in the vertical direction is vertically bent due to the entire reflection action of the slit 32 to be introduced to the core 12. COPYRIGHT: (C)2004,JPO
