Abstract
A method and apparatus for performing free space optical interconnection. A micro-mirror type of spatial light modulator has an array of mirror elements, whose height with respect to a deflection plane can be individually adjusted. These heights are adjusted such that an input beam of light is phase modulated, and by interference, it is deflected to a desired detector. More than one input beam can be used with the same spatial light modulator, whose mirror elements are adjusted in patterns for deflecting and focussing to multiple detectors.
