Abstract

All-optical logic gates are the basic components of all-optical signal processing and computing. Among all other logic gates, exclusive-OR (XOR) plays a significant role on optical computing, switching, and networking. We propose a novel and simple scheme for all-optical exclusive-NOR and XOR logic gates using single mode Fabry-Pérot laser diode (SMFP-LD). The logic gates are based on the multi-input injection locking and supporting beam principle to suppress the intensity of the dominant mode of the SMFP-LD. The working principle of the proposed scheme is explained, and the experimental results are presented at the data rate of 10 Gbps input signals for the logic operations. We observed clear eye openings with an extinction ratio of about 12 dB and a rising/falling time of about 35 ps of the logic outputs. The demonstrated scheme can be used to implement all-optical computing and switching networks.
