The effect of dispersion on an all-optical logic XOR gate is simulated and investigated. This Boolean function is realized by using semiconductor optical amplifiers-based Mach–Zehnder interferometer (SOAs-MZI). The dependence of the output quality factor (Q-factor) on input pulse energy, pulse width, SOA’s carrier lifetime, linewidth enhancement factor (α-factor) and saturation power has been examined and assessed. The obtained results confirm that the XOR gate implemented with the proposed scheme is capable of operating at a data rate of 80 Gb/s with logical correctness and high output Q-factor.
