256 × 256 Turnover-type free-space multichannel optical switch based on polarization control using liquid-crystal spatial light modulators.

Free-space multichannel optical switches using polarization control are attracting interest for future telecommunication networks and interconnection networks in computers. We describe a switching architecture, the turnover type, for such free-space multichannel optical switches. The architecture makes it possible to realize a large-scale and transparent… CONTINUE READING
