Abstract
Optical MCM require both optical and electrical connection interfacingto the rest of the system. Although the earlier demos utilized bothsurfaces of the MCM such that top surface is for optical connectionand bottom for electrical. However, because the top surface is alsoused for the cooling, use of top surface for optics results incomplicated structure or imperfect cooling. Therefore we designed lensand LGA based simultaneous optical and electrical connection throughthe bottom surface of the MCM. We discuss the details of the design aswell how to realize the necessary components.
