Abstract :
A rearrangeable free-space optical multichannel switch using the polarisation multiplexing technique is examined. The switch consists of LCTV polarisation switches and routing elements. It is shown that the switch is suitable for network reconfiguration in parallel processing systems. A 32-channel prototype optical switch was constructed, and excellent switching performance and stable insertion loss were confirmed.
