ABSTRACT:
The present invention provides an optical rearranging device that is simple, compact, highly efficient, and is located in the proximity of an image plane. This device utilizes diffractive, refractive, and/or reflective elements and can produce a perfect shuffle or other interconnect pattern that is useful in computing, communication, and switching applications involving optically carried information. Further, this device can be made from redirecting elements that are themselves switchable, thus enabling a direct switching between the non-rearranged interconnect pattern and other rearranged interconnect patterns.
