Abstract:
1. An optoelectronic (OE) assembly for a semiconductor or computer chip, comprising: a silicon layer with wiring, the silicon layer defining at least one optical via for allowing light to pass therethrough from a light source; 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 OE elements coupled to the silicon layer and electrically communicating with the wiring, at least one of the OE elements positioned in optical alignment with the optical via for receiving the light, the silicon layer and the wiring being between the OE elements and the optical coupling layer, and the OE elements being in spaced relation with the optical coupling layer having the wiring therebetween; a carrier for interposing between electrical interconnect elements, the carrier including a recessed portion which houses the OE elements, the carrier being positioned between the wiring of the silicon layer and a circuit board and electrically connecting first interconnect elements connected to the wiring of the silicon layer and second interconnect elements connected to the circuit board; and a heat spreader positioned between a bottom surface of the recessed portion and a bottom surface of the OE elements, the heat spreader being configured to provide thermal conductivity from the OE elements.
