Patent ID: 8559474

Claim:
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; 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; and a carrier and thermal sink interposer positioned over the OE elements, said carrier including an alignment frame bonded thereto, said alignment frame including an alignment feature for positioning the carrier in mating relation with the optical coupling layer, said carrier laterally conducting heat from said silicon layer to the thermal sink interposer via said alignment frame.
