An acousto-optic architecture is presented to implement a nonblocking space-division switch with O(N) complexity. Signal degradation is minimal so that the switch is suitable for nonregenerative application within optical networks; it is also capable of rapid reconfiguration. Experiments for a 1 × 4 switch show an insertion loss ranging from 4.6 to 5.6 dB, a worst-case signal-to-cross-talk ratio of better than 30 dB, and a reconfiguration time of 1.46 μsec.
