AB - Dynamic free-space optical routing system is experimented by a holographic crossbar with single-stage switching architecture. For dynamic operation, electrically addressed liquid- crystal spatial light modulator and diffraction gratings are used in place of passive holograms. Diffraction gratings are consisted of regular cells and have multiple phase delays. This pixelated kinoform phase grating array displayed on SLM deflects a input beam toward a wanted direction or splits a input beam into many beams and then steers them to desired positions. Each grating array is combined with three periods of grating which is constructed by 32 X 32 pixels with equally space phase levels. This system has higher efficiencies and superior characteristics of beam split, and produces asymmetric output beam pattern. In this system, input ports are 3 X 3 and output ports are 5 X 5. It operates at high speed as dynamic free-space optical switch and leads low optical losses.
