A novel all-optic waveguide crossbar switch based on an in-house developed birefringent material is presented here. This switch uses visible light ((lambda) equals 514 nm) for programmable beam addressing to provide all-optic reconfiguration in both single-mode and multi-mode waveguides. An array of waveguide beams can be addressed within milliseconds using very moderate optical pumping powers (below 100 (mu) W). This allows green emitting diodes to be used for signal switching. The switch is characterized by high speed, high switching sensitivity, low waveguide loss, low optical noise levels, erasability, and reasonable cost.
