Abstract

A fiber optic switch using MEMS is scalable by the use of a matrix of cross-points located at the intersection of all possible input and output light paths. Cross-points are formed by a MEMS procedure where a digitally movable mirror intersects a light path to provide a digital switching action with the remaining cross-point mirrors being moved out of position to provide through transmission.
