ABSTRACT:
An arrangement for optically coupling a planar optical waveguide and an optical fiber comprises forming a planar optical waveguide on a surface of the substrate, forming a trench-like depression in the surface of the substrate leading from an end face of the planar waveguide to an edge of the substrate, forming a second holder part having a fiber secured between two planar surfaces lying in a common plane, assembling the separate holder part on a pair of planar surfaces lying on each side of the depression of said substrate so that the fiber is placed in the depression with play and the fiber will be arranged with the axis of the fiber being aligned with the axis of the planar waveguide.
