    摘要： A controller of an optical axis aligning apparatus carries out quadric surface approximation with a plane parallel to a connecting end face of an optical component or an optical fiber, in order to align the emission axis of the optical component and the optical axis of the optical fiber in connecting the component and the fiber, and then carries out quadric function approximation in the direction of an axis perpendicular to the plane related to the quadric surface approximation, thereby securely finding a maximum light quantity point at a lower frequency of stage operation in the aligning apparatus to shorten the tact time for optical axis alignment.

    摘要： An optical fiber array includes a plurality of optical fibers which are arranged and fixed in a fiber array member. The optical fibers each have an end projecting from an end face of the fiber array member at substantially the same distance, and each have a lens formed at the end thereof. The optical fiber array is produced by arranging and fixing a plurality of optical fibers in the fiber array member such that each end of the optical fibers is projected from the end face of the fiber array member; forming a coating layer of a desired thickness over the end face of the fiber array member and portions of the optical fibers projecting from the end face of the fiber array member; collectively polishing the ends of the optical fibers projecting from the end face of the fiber array member, together with the coating layer, up to a predetermined position, thereby making the lengths of projections of the optical fibers substantially equal; and removing the coating layer and forming a lens at each end of the optical fibers.

    摘要： A quartz-based optical fiber with a lens, wherein a lens shaped in a curved surface is directly formed on an end surface, and its manufacturing method are provided, the quartz-based optical fiber with a lens having a lens section formed by a projecting core shaped in a curved surface on the end surface, the lens section being produced by immersing the end surface section of the quartz-based optical fiber, which consists of a core and a clad having a composition in which the etching speed is higher than that of the core when a hydrofluoric acid solution is applied, in the hydrofluoric acid solution to cause a core shaped in a truncated cone to project from the end surface of said quartz-based optical fiber, then heating and melting the core shaped in the truncated cone and the vicinity thereof, thus changing the truncated cone shape into a curved surface shape.
