Abstract

Abstract An optical/electrical connector including a molded base having a well and a plurality of grooves extending from the well to a first outer edge of the base and alignment guides associated with the grooves at the first outer edge. The base further having external electrical connections with first ends exposed and positioned in the well and second ends extending outwardly beyond a second outer edge of the base. An array of photonic components is positioned in the well and each aligned with a separate groove. The array is electrically coupled to the exposed first ends of the external electrical connections of the base. The grooves are filled with a plastic material to form optical waveguides from the optical ports to the first outer edge.
