Abstract
A coupling arrangement for optically coupling a fiber to a planar optical waveguide integrated on a substrate, such as employed in silicon micromechanical units. The substrate together with the waveguide and a cover member placed over the waveguide form component parts of a carrier member. The carrier member is fashioned such that the end of the waveguide lies in an end face of the carrier member. Two triangular openings between which the waveguide is arranged, are fashioned in the end face of the carrier member. The end face of the carrier member has a dimension similar to an outside diameter of the fiber and the end face of the fiber has its outer circumference welded to the end face of the carrier member.
