Abstract
Both multichip modules (MCMs) and optical interconnects are expected to play a pivotal role in the development of high performance electronic systems. Only by packaging optoelectronic components within the multichip modules can the advantages of both technologies be realized. We have demonstrated the incorporation of optoelectronic components into two different MCM technologies. In the first, we have used existing equipment and proven polymer materials to implement optoelectronic interfaces in a high density 'chip-first' technology. In the second, we have demonstrated optoelectronic packaging in 'chip-and-wire' packaging schemes. In both cases, the optical characteristics are compatible with commercial vertical cavity surface emitting lasers and optoelectronic receivers, allowing the implementation of practical MCM-to-MCM interconnects.
