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.
