ABSTRACT:
The present invention is an efficient system and method for cascading optical switches in architectures that enable three dimensional multi-plane optical signal beam steering to be performed with two dimensional steering devices. A plurality of cascaded optical switches form a cascaded multi-plane optical switch fabric and direct an optical signal beam from one of the plurality of optical switches to another of the plurality of optical switches in a different plane. In addition, a multi-plane directional device directs an optical signal beam from a first optical switch stage to a second optical switch stage oriented in a different plane. Furthermore, a fixed incidence corrective device directs an optical signal beam in a shallow angle to an optical switch located in a relatively close proximity on the optical switch fabric and a optical signal beam spread correction device provides for refocusing of spreading optical signal beams and mitigation of signal loss.
