ABSTRACT:
The present invention cascaded optical switching system includes architectures that provide three dimensional optical signal beam steering utilizing two dimension optical signal beam steering devices. A plurality of cascaded optical switches form a cascaded multi-dimensional 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 dimension. In one embodiment, an incidence corrective device is included in a cascaded optical switch fabric and directs an optical signal beam in a shallow angle so that it strikes the next optical switch at a corrected incidence angle. A corrected incidence angle permits an optical signal beam to be forwarded at a relatively shallow angle to an optical switch located in a relatively close proximity on the optical switch fabric. The present invention also provides for refocusing of spreading optical signal beams and mitigation of signal loss.
