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 with clear temporal waveform and wide eye opening is achieved in five parallel channels simultaneously. The extinction ratios are >10.3 dB, while the optical signal-to-noise ratios are >21 dB. Based on the demonstrated scheme, a method of realising simultaneous full set of two-input logic operations is proposed and discussed. The proposed scheme can be extended to higher data rates and transferred to on-chip platforms.
