This paper provides an overview of linearization of two different microwave photonic links based on phase modulator and dual-electrode Mach–Zehnder modulator. It takes into account the problem of intermodulation distortion which can severely degrade the performance of the system. Spurious free dynamic range has been analyzed through numerical and simulation for both the modulator links which are linearized using mixed polarization. Improvements of 7.3 dB and 15.1 dB are found in SFDR using polarizers in phase and Mach–Zehnder modulator, respectively.

基于偏振器的不同调制器的微波光子链路的比较分析

本文概述了基于相位调制器和双电极Mach–Zehnder调制器的两个不同微波光子链路的线性化。它考虑到互调失真的问题，该问题会严重降低系统的性能。通过数值和仿真分析了使用混合极化线性化的两个调制器链路的无杂散动态范围。分别在相位和Mach–Zehnder调制器中使用偏振器，可以在SFDR中获得7.3 dB和15.1 dB的改进。
