Programmable optical interconnections with large fan-out capability using the magneto-optic spatial light modulator

We report the use of two-dimensional, binary phase-only diffraction gratings written on a programmable magnetooptic spatial light modulator to interconnect optically an input laser beam to multiple output locations. We show that we can achieve programmable weighted interconnects between the source and two output locations as well as a fan-out capability to as many as 128 separate output locations.
