Abstract
A novel optical path switching system, architecture and technique wherein light beam data traffic is to be switched by MEMS mirrors between source and destination nodes, and test ports are used to set up optical paths even before the real data traffic is propagated, with a combination of an electrical mirror-sensing feedback loop for controlling coarse mirror positioning, and an optical path power-sensing feedback loop for controlling fine adjustments in the mirror position.
