Abstract:
A free-space optical interconnection device comprising:(a) at least one input light source, said at least one input light source adapted to generate an array of light beams;(b) a plurality of optical elements configured so as to define a plurality of possible light paths for each said light beam in said array;(c) a spatial light modulator adapted to select a path from among said light paths for each pass of a said light beam through said optical elements and reflect the light beam to said selected path, each said light beam making multiple passes through said optical elements; and(d) an output plane adapted to receive each said light beam emerging from said optical elements, said output plane having at least two dimensions, the resultant position of each said light beam on the output plane determined in one said dimension by the position of said light beam in one dimensional input array and in the other said dimension by said light paths traveled by said light beam through said optical elements.
