Paper Abstract

One of the main challenges involved with the successful implementation of free-space optical interconnections is associated with the issue of misalignment. Small misalignments of the components can substantially decrease the coupling efficiency between the source and detector. The alignment problem can be tackled in various ways: the most straightforward solution consists in designing the system to be as misalignment tolerant as possible by using slow f- number beams, oversized apertures or a beam clustering design. Having chosen a suitable design it is then necessary to implement it in such a way that the possible misalignments of each component are minimized, while requiring minimal active alignment control. This paper reports on the implementation of a dense 256-channel free- space multistage optical system which interconnects 4 optoelectronic VLSI chips in a square baseplate 7 cm on a side. Alignment strategies, constraints and experimental results are presented.
