The calibration of the numerous mirror pairs, or switches, in MEMS-mirror optical cross-connect systems is a critical process in their manufacture. Because the number of switch connections for these systems scales quadratically to the number of inputs/outputs, this places great demands on the equipment used to perform testing. We propose and demonstrate a calibration technique for generic optical subsystems based on optical time-division multiplexing (OTDM).
