ABSTRACT:
The present invention is an efficient system and method for cascading optical switches. A plurality of cascaded optical switches form a cascaded 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 one embodiment of the present invention, a variable incidence corrective device is included in a cascaded optical switch fabric. The incidence corrective device 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.
