Self-routing optical crossbar switch

A self-routing optical crossbar switch in which wavelengths of tag light represent the information of destination address by using an optically addressable spatial light modulator as the 3-D crossbar switch along with a wavelength filter for tag light. A BSO (Bi/sub 12/SiO/sub 20/) spatial light modulator was used to perform a 1*2 self-routing switching experiment with two different wavelengths of tag light. The implementation to scale-up the throughput of the switch is also presented.<
