Optical switch fabric for individually switching optical paths for optical signals between input and output ports

摘要

The invention relates to an optical switch fabric comprising at least one micro mirror array with tilting micro mirrors for individually switching optical paths for optical signals between input and output ports, especially fibers or waveguides gathered in at least one fiber arrays, comprising a beam splitter and a detector array, wherein the beam splitter is adjusted to partly reflect the optical signals reflecting from the mirrors of said at least one micro mirror array to said detector array and micro mirror control means, that are realised such, that a control signal is generated out of a feedback signal of said a detector array to correct the angular positions of the micro mirror and a method therefore.
