摘要： A predetermined number of optical fibre parts (27) is provided on a rectangular frame (1), the fibre parts extending parallel to each other along a straight line between two opposite first sides (3) of the frame. These first sides (3) comprise comb-shaped fibre guides (5) with teeth (13), between which the fibre parts (27) are guided so that the fibre guides determine a first relative distance between the fibre parts. The first sides (3) are pivotably connected to the two second sides (7) of the frame (1), which is then deformed to a parallelogram until the portions of the fibre parts (27) located inside the frame have a predetermined second relative distance. A permanent connection between the fibre parts (27) is established so that a ribbon of fibre parts is obtained. A number of such ribbons can be stacked with the interposition of strip-shaped spacers (29) to form a bundle.

摘要： A method of manufacturing one or more magnetic heads starts from a substrate (11) on which a first magnetic layer (13) is provided. A recess (15) is formed in this layer at the location of a transducing gap to be formed, after which a gap layer (19) is provided on a bounding wall (17) of the recess. Subsequently, the recess is filled with a second magnetic layer (23) and a counterblock (31) is provided on the layers after surface-polishing. Finally, a winding aperture is provided.

摘要： To a carrier (1, 1') there is cemented a bar of a material (3, 3'), for example glass or a ceramic material, which is subsequently divided, using cuts (7, 7') which extend transversely of its longitudinal direction, into a number of slices (9, 9') which are separately cemented to the carrier. Each slice (9, 9') is provided with a groove (13, 13') which extends parallel to the cuts (7, 7'). The grooves (13, 13') are curved and have a center of curvature which is situated at the side of the bar (3, 3') which faces the carrier (1, 1'). In the grooves (13, 13') there are secured optical fibres (19, 19') which follow the curvature of the groove, after which a side portion of the fibres which is situated furthest from the carrier (1, 1') is ground off. A flat ground face (21, 21') is thus formed one each fibre (19, 19'). Such ground fibres (19, 19') are arranged so that their ground faces contact one another in order to form directional couplers, after which the slices (9, 9') are detached from the carrier (1, 1').

摘要： A passive fiber optic component, in which two or more fibers are each bared at one end by removal of the outer coating of the fiber. The bare portions of the fibers are etched to produce cylindrical end portion which adjoins a conical portion. Subsequently, the fibers are arranged with their etched portions in a capillary tube which is sealed at one end. The tube is then evacuated and is fused with the etched portions of the fibers to form a solid rod with a rotationally symmetric distribution of the end portions of the fibers. The fibers are etched to such a diameter that after fusion of the fibers with the tube, the fused fiber ends have a circular cross-section substantially equal to the cross-section of a single fiber core. An end face is formed on the rod by cleaving or by grinding, and by polishing to obtain a fused fiber head. The fiber head forms a fiber optic component itself, or forms a basic element for a great number of fiber optic components such as splitters and couplers.

摘要翻译： 一种制造无源光纤部件的方法，其中两个或更多个光纤在一端分别通过去除光纤的外部涂层而被光刻的裸露部分产生圆柱形端部，该圆柱形端部邻接圆锥形部分 。 随后，将纤维（1）与其蚀刻部分一起设置在一端密封的毛细管中。 然后将管抽出并与纤维的蚀刻部分熔合以形成具有纤维端部的旋转对称分布的实心棒。 纤维被蚀刻到这样的直径，即在纤维与管融合之后，熔融纤维的端部具有基本上等于单个纤维芯的横截面的圆形横截面。 通过切割或研磨在杆上形成端面，并通过抛光形成熔融纤维头。 光纤头本身形成光纤部件，或形成用于大量光纤部件如分束器和耦合器的基本元件。
