| English abstract | The modeling of all-optical logic XNOR gate is realized by a series combination of XOR and INVERT gates. This Boolean function is simulated by using Mach–Zehnder interferometers (MZIs) utilizing quantum-dots semiconductor optical amplifiers (QDs-SOAs). The study is carried out when the effect of amplified spontaneous emission (ASE) is included. The dependence of the output quality factor (Q-factor) on signals and QDs-SOAs’ parameters is also investigated and discussed. The simulation is conducted under a repetition rate of ∼1 Tb/s |
