ABSTRACT: "Method of manufacturing a plurality of optical components" 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 centre 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 on 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').
