Abstract: In one aspect of the invention there is provided a retainer (150) for retaining a first section of an elongate element (13) of generally curvilinear cross section in a mounting channel (18) which extends along a surface (24) of a first side of a substrate (23) from an edge (25) at which a second side (27) of the substrate inclines away from the first side in a first direction. The retainer has a mounting surface (170) adapted in use to be mounted on the surface of the first side of the substrate, a first retaining channel (156) formed in the mounting surface adapted in use to cover the first section of the elongate element in the mounting channel, an overhanging surface (172) adapted in use to overhang the edge of the first side of the substrate, the overhanging surface being displaced, in use, in the first direction relative to the mounting surface, and a second retaining channel (156) formed in the overhanging surface adapted in use to be positioned about a second section of the elongate element which projects from the mounting channel. In another aspect of the invention there is provided a coupling device (11) for coupling an optical fibre (13) to a package (1) which has an indexing feature (34) adapted to co-operate with an indexing feature (37) on an optical fibre cleaving apparatus. In a further aspect there is provided a method of guiding an optical fibre (13) into a mounting channel (18) in a substrate (23) through use of a tapered guide channel (56) in a guide element (50). In a yet further aspect of the invention there is provided a substrate (223) for an optical chip having a side with a surface (224) in which there is formed a first channel (218) for an optical fibre (13) to be mounted in and a second channel (218a, 218b) which is oriented transversely to, and in communication with, the first channel.
