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, the underside of the third substrate being displaceable on the top side of the first substrate for laterally adjusting the lens with respect to the electrooptical component.
