Abstract:
An optical interconnection device comprising:at least one input light source, each said input light source adapted to introduce at least one individual light beam; a first optical configuration, said first optical configuration comprising a first plurality of optical elements so as to define a plurality of possible light paths for each said individual light beam, said first optical configuration adapted to receive each said individual light beam emerging from each said input light source, said first optical configuration further adapted to direct a said light beam to a spatial light modulator; a second optical configuration, said second optical configuration comprising a second plurality of optical elements configured so as to define a plurality of possible light paths for each said individual light beam, said second optical configuration further comprising at least one spot displacement device, said second optical configuration adapted to receive as input a said individual light beam reflected from said spatial light modulator, said second optical configuration further adapted to direct a said individual light beam to said spatial light modulator; and said spatial light modulator comprising at least one column, each said column comprising at least two rows, said spatial light modulator adapted to select a given path from said plurality of possible light paths for a light beam, wherein said spot displacement device is operable for shifting a said individual light beam on said spatial light modulator by at least one row.
