Patent ID: 8483253

Claim:
An optoelectronic (OE) package comprising: an integrated OE assembly adapted for mounting on a circuit board via an interposer device, said integrated OE assembly 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; at least one first OE element coupled to the silicon layer and electrically communicating with the wiring layer, the first OE element positioned in optical alignment with the optical via for receiving the light; and a laser diode driver (LDD) device embedded within the wiring layer; and said interposer device comprising: a carrier positioned between the integrated OE assembly and said circuit board and having conductive wiring for providing electrical communication between first conductive interconnect elements that connect said integrated OE assembly to said carrier and second conductive interconnect elements that connect said carrier to said circuit board, the carrier including a respective surface cavity corresponding to an OE element within which the corresponding first OE elements protrudes.
