N2 - The performances of all-optical logic XOR, AND and OR gates have been simulated. These Boolean operations are realized by using a Mach-Zehnder interferometer utilizing semiconductor optical amplifier (SOA) with quantum-dot (QD) active region. The study is carried out when the effect of amplified spontaneous emission is taken into account in the simulation analysis. Results show that these logic gates are capable of operating at a data speed of 250 Gb/s with high output quality factor (Q -factor). The dependence of the output Q -factor on signals and QD-SOA parameters is also investigated and discussed.
