40 Gbit/s all-optical XOR gate based on hybrid-integrated Mach-Zehnder interferometer

A Frequency Domain Systems Theory Perspective for Semiconductor Optical Amplifier - Mach Zehnder Interferometer Circuitry in Routing and Signal Processing Applications

“…Particular attention has been paid to the all-optical XOR gate that forms a key technology for implementing primary systems for binary address and header recognition, binary addition and counting, pattern matching, decision and comparison, generation of pseudorandom binary sequences, encryption and coding. This gate has been demonstrated at 40 Gb/s (Webb et al 2003) using SOA-MZI schemes. Figure 1 (c) presents the principle of Boolean XOR operation.…”

Novel All-Optical On-Off Keyed to Alternate-Mark- Inversion Converter

“…The SOA-based MZI is configured as an exclusive-or (XOR) logic gate [2,3], as shown in Fig. 1, with two input ports, A and B.…”

IST-LASAGNE: towards all-optical label swapping employing optical logic gates and optical flip-flops

“…Although the architecture has been simulated at 10 Gb/s, this can be extended to 40 Gb/s optical labels by employing a differential scheme at the SOA-MZI inputs [27].…”
