Abstract A novel Microwave Photonic Link (MPL) system configuration based on two Dual-drive Dual-parallel Mach-Zehnder modulators (D-DPMZMs) and two Balanced Photo-Detectors (BPDs) is reported. The Intermodulation Distortions (IMDs), as well as the harmonic distortions have been eliminated. The proposed linearization of RF signal configuration is double side banded in both D-DPMZM. A full mathematical model has been developed and simulations have been implemented for the proposed configuration. The RF linearization for this configuration has been tested by introducing an additional RF signal, as well as phase and intensity errors in MZ branches. The proposed MPL system configuration exhibits significant performance and it will have great impact on aerospace, radar, and satellite-to-ground downlink communication system applications.

AbstractA scheme to suppress nonlinear intermodulation distortion in microwave photonic (MWP) link is proposed by using polarizers to compensate inherent non-linear behavior of dual-electrode Mach-Zehnder modulator (DE-MZM). Insertion losses and extinction ratio have also been considered. Simulation results depict that spurious free dynamic range (SFDR) of proposed link reaches to 130.743 dB.Hz2/3. A suppression of 41 dB in third order intermodulation distortions and an improvement of 15.3 dB is reported when compared with the conventional link. In addition, an electrical spectrum at different polarization angles is extracted and 79^\circ is found to be optimum value of polarization angle.
