Title: Electrooptical coupling component

Abstract: A coupling component includes a first substrate with a first alignment device and a plurality of optical waveguides located in one plane. The first substrate is a molded synthetic material body. The optical waveguides have coupling-side end surfaces causing a beam deflection onto optically active surfaces of a multichannel electrooptical converter. A second substrate has a second alignment device tuned or matched to the first alignment device of the first substrate. The converter is positioned on the second substrate independently of the optical waveguides and precisely with respect to the second alignment device. The alignment devices are formed by corresponding oblique surfaces on both substrates. The oblique surfaces in one dimension extend parallel to the longitudinal axes of the optical waveguides and are located in planes which intersect the plane of the optical waveguides. The oblique surfaces effect a form-locking engagement, as a result of which the end surfaces are laterally adjusted relative to the optically active surfaces.
