Abstract
An optical network element using arrays of mirrors in an optical switch. A lens system is placed in between the mirror arrays and optical signals are passed through the lens system in an off-axis manner in order to increase switching capacity so that larger arrays of mirrors can be used, shorten the optical path through the switch or a combination of both.
