Abstract:
1. An optoelectronic (OE) assembly for a semiconductor or computer chip, comprising: a silicon layer including a wiring layer, the silicon layer defining at least one optical via for allowing light to pass therethrough; an optical coupling layer bonded to the silicon layer, the optical coupling layer including a plurality of microlenses for focusing and or collimating the light through the optical via; a plurality of first OE elements coupled to the silicon layer and electrically communicating with the wiring layer, the first OE elements positioned in optical alignment with the optical via for receiving the light; a second OE element embedded within the wiring layer; the first OE elements being attached beneath the silicon layer and electrically communicating with the wiring, and the first OE elements being positioned in optical alignment with the optical via for receiving the light; a carrier including conductive wiring, the carrier electrically communicating with a plurality of wiring layer interconnect elements for attaching the assembly to the carrier, and the carrier electrically communicating with the wiring layer, the carrier being interposed between a plurality of electrical interconnect elements connected to a circuit board, and the plurality of wiring layer interconnection elements; and the carrier including a plurality of recessed, portions for housing the first OE elements, respectively.
