Patent ID: 7630598

Claim:
An optical cross-connect device for shifting the location of one or more light beams in an array of light beams comprising: an input array for inputting an array of light beams; a lens; a plurality of microelectrical-mechanical devices; and a plurality of mirrors; wherein the microelectrical-mechanical devices are located at a distance away from the principal planes of the lens that is approximately equal to the focal length of the lens; wherein the microelectrical-mechanical devices comprise controllable pixels for directing one or more light beams in the array of light beams through the lens and onto two or more of the plurality of mirrors; wherein the two or more of the plurality of mirrors are located at a distance away from the principal planes of the lens that is approximately equal to the focal length of the lens and are located generally opposite of one or more microelectrical-mechanical devices; wherein each of the two or more of the plurality of mirrors are positioned at different angles with respect to one another so that light beams incident on each mirror are shifted differently with respect to one another as they land on a subsequent microelectrical-mechanical devices.
