Abstract:
1. An optoelectronic assembly for a computer system, comprising: an electronic chip set; a printed circuit board; a substrate disposed between the electronic chip set and the printed circuit board, the substrate comprising a first major surface opposing a second major surface, wherein the first major surface is in communication with the electronic chip set, and wherein the second major surface is in electrical communication with the printed circuit board; an electrical signaling medium having a first end in signal communication with the substrate; an optoelectronic transducer in signal communication with a second end of the electrical signaling medium; and an optical coupling guide for aligning an optical signaling medium with the optoelectronic transducer; wherein an electrical signal from the electronic chip set is communicated to the optoelectronic transducer via the substrate and the electrical signaling medium, and wherein the electronic chip set and the optoelectronic transducer share a common thermal path for cooling; a heat spreader having a first and second surface, the first surface in thermal contact with the electronic chip set and adapted to provide unimpeded heat flow, and the second surface in thermal contact with the optoelectronic transducer, the first surface being orthogonal to the second surface, the optoelectronic transducer being mounted on the second surface.
