Abstract
An optoelectronic apparatus is presented. In embodiments, the apparatus may include a package including a substrate with a first side and a second side opposite the first side, wherein the first side comprises a ball grid array (BGA) field. The apparatus may further include one or more integrated circuits (ICs) disposed on the first side of the substrate, inside the BGA field, that thermally interface with a printed circuit board (PCB), to which the package is to be coupled, one or more optical ICs coupled to the second side and communicatively coupled with the one or more ICs via interconnects provided in the substrate, wherein at least one of the optical ICs is at least partially covered by an integrated heat spreader (IHS), to provide dissipation of heat produced by the at least one optical IC.
