N2 - The ultrafast performances of all-optical logic XOR, AND and OR gates are numerically simulated. These Boolean operations are realized by employing the quantum-dots semiconductor optical amplifiers (QDs-SOAs). The theoretical study is carried out when the effect of amplified spontaneous emission (ASE) is taken into account in the simulation analysis. The dependence of the output quality factor (Q-factor) on signals and QD-SOA's parameters is also investigated and discussed. The obtained results indicate that these all-optical logic gates are capable of operating at 1 Tb/s with high output Q-factor provided that these parameters are properly optimized.
