All-optical reconfigurable multicast canonical logic units based on four-wave mixing

Canonical logic units (CLUs) are basic building blocks for complex all-optical logic operations, and multicast of CLUs can improve the computing capacity and operating flexibility. The authors thus propose and experimentally demonstrate all-optical reconfigurable multicast two-input CLUs (i.e. minterms) at 40 Gb/s by using four-wave mixing in a single highly non-linear fibre. Each type of CLUs wit...
