Abstract: An optical coupling array having a first substrate with an electrooptical component, a second substrate having at least one optical fiber end and being formed with a recess open towards the underside of the second substrate and being defined by a mirror face oriented towards the optical fiber end, and a third substrate including at least one lens and being disposed between the first substrate and the second substrate, a beam path extending from the optical fiber end to the electrooptical component via the mirror face and the lens, includes an extension formed on the third substrate and fitting form-lockingly into the opening of the recess on the underside of the second substrate, the extension having a side face forming at least one reference face cooperatable with a corresponding reference face of the second substrate for laterally positioning the third substrate and the lens relative to the second substrate, the top side of the third substrate being solidly joined to the underside of the second substrate, t

Abstract: An electro-optical module includes a substrate having a given surface with first and second lines. An electro-optical unit has a plurality of electro-optical elements being fixed in the first line on the given surface. A corresponding plurality of recesses is formed in the second line on the given surface. Lenses are fixed in the recesses opposite the electro-optical elements, for coupling the electro-optical elements with further optical elements. At least two alignment fixtures are formed on the given surface and are offset from the second line toward the electro-optical unit. Bodies are each disposed in a respective one of the alignment fixtures and act as a mechanical stop for the electro-optical unit.
