Inter-Chip Optical Interconnects are viable alternatives for conventional copper wires. However, the costly assembly and packaging process is the major obstacle to their commercial breakthrough, where especially the coupling of optical components seems to be the most critical aspect.
This paper describes the packaging and 3-D coupling scheme we have developed for a 2-D parallel optical interconnect module with on-chip access. It is a passive index alignment method that measures the coordinates of alignment features to achieve correct alignment. We belief it is a possible low cost solution as full automation is possible.
