A space-division multiplexing switch was fabricated without precise alignments using electro-photonic multi-chip module technologies. Design rules and fabrication processes for the switch are described. Experiments show the switch has capacity for 1-Gigabit-per-second data transmission.
Key words : optical interconnection, optical switch, free-space optics, space-division multiplexing, packaging, alignment-free, vertical-cavity surface-emitting laser
