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.
