Abstract

The nonlinear effect of two-photon absorption (TPA) on the performance of all-optical XOR gate using quantum dot semiconductor optical amplifiers (QDSOAs)-assisted Mach–Zehnder interferometer is numerically analyzed and investigated at a data rate of 2 Tb/s. The dependence of the quality factor (QF) on the critical parameters of the input signal and QDSOA is examined and assessed. The obtained QFs for the all-optical XOR gate using QDSOAs-MZI at 2 Tb/s with TPA and without TPA are 14 and 8, respectively.
