We propose a scheme to realize all-optical logic operation in quantum-dot semiconductor optical amplifier (QD-SOA) based Mach-Zehnder interferometer (MZI) considering the effects of two-photon absorption (TPA). During propagation of sub-picosecond pulses in QD-SOA, TPA leads to an additional change in carrier recovery dynamics in quantum-dots. We utilize a rate equation model to take into account carrier refill through TPA and nonlinear dynamics including carrier heating and spectral hole burning in the QD-SOA. The simulation results show the TPA induced pumping in the QD-SOA can reduce the pattern effect and increase the output quality of the all-optical logic operation. With TPA, this scheme is suitable for high speed Boolean logic operation at 320 Gb/s.
