120 Gb/s optical card-to-card interconnect link demonstrator with embedded waveguides

We report on a card-to-card optical interconnect demonstrator with passively aligned butt-coupled optoelectronic modules onto waveguides embedded into the printed circuit board (PCB). After describing selected building blocks, we will present experimental results obtained with the demonstrator hardware consisting of a parallel 12-channcl at 10 Gb/s (120 Gb/s) optical card-to-card link. © 2007 IEEE.
