A dynamic optical interconnection system is experimented by a holographic crossbar. The pixelated multi-phase grating array displayed on spatial light modulator generated a beam array onto an arbitrary position with high efficiency in the output plane. The system operates at high speed as a free-space optical switch.
Key words : multi-phase grating, spatial light modulator, optical interconnection, holographic crossbar, computer-generated hologram, optical switching
