“…It is crucial to notice that SOA-MZI low pass behavior degraded the mixed signal for about 35 dB at 158 GHz at any carrier frequency. However, the modulation principle played a significant role in amplifying the electrical power of the sampled signal compared to the switching principle [22,35]. This resulted in higher conversion gains.…”

“…The architecture of the real SOA-MZI used in simulations by the VPI simulator is given in Figures 1 and 2, which is already proposed in our previously published work [34,35]. One SOA was located in each arm of the MZI.…”

“…It is worth noting that the only difference between this work and that in Ref. 16 is that the sampling signal and the data signal are exchangeable signals. In other words, the sampling signal is injected at the MP of the SOA-MZI while the data signal is entered into the CP of the SOA-MZI.…”

“…After that, the EVM values are calculated from the measured BER. Since the sampled signal follows the harmonics of the sampling signal where its harmonics power slightly decreases at the SOA-MZI output due to the wavelength of the optical filter that is equal to the wavelength of the sampling signal, 16 the performance of the mixing system is enhanced sufficiently. It is worth noting that the only difference between this work and that in Ref.…”

“…Semiconductor optical amplifiers (SOAs) rely on their nonlinearity such as cross-gain modulation (XGM) [10] and XPM [11][12][13][14][15][16][17][18][19][20] can also be used for shifting at the same time in the layout of a detached apparatus or implemented in an interferometric structure such as an SOA-Mach-Zehnder Interferometer (SOA-MZI). SOA-MZIs can achieve good performance, such as a frequency range up to 100 GHz [19].…”
