摘要

摘要本文介绍了通过改变双驱动双并联马赫-泽恩德调制器（DD-DPMZM）的移相器排列生成线性化光子信号的不同方案的性能分析。DD-DPMZM 子调制器电极上的射频信号通过不同的相位角馈入，从而在输出端产生光调制信号。拟议的系统由 DD-DPMZM 和移相器组成。针对 DD-DPMZM 上下臂子调制器的不同配置，对无杂散动态范围（SFDR）进行了评估。通过完全抑制三阶互调失真，上下子调制器的正交和光载波抑制调制的 SFDR 达到 135.6 dB Hz4/5。它是基于双并行马赫-泽恩德调制器的线性微波光子链路的高性能配置。

Performance study of microwave photonic links by considering the effect of phase shifters and bias conditions on dual-drive dual parallel Mach–Zehnder modulator

Abstract This paper presents the performance analysis of different schemes for generating linearized photonic signal by varying phase shifter arrangements of a dual-drive dual parallel Mach–Zehnder modulator (DD-DPMZM). The RF signals at the electrodes of sub-modulators of DD-DPMZM are fed using different phase angles to generate optically modulated signals in the output. The proposed system consists of a DD-DPMZM and phase shifters. Spurious free dynamic range (SFDR) is evaluated for different configurations of sub modulators in upper and lower arm of DD-DPMZM. SFDR of 135.6 dB Hz4/5 is obtained for quadrature and optical carrier suppression modulation in upper and lower submodulators by suppressing third order intermodulation distortion completely. It is found to be high performance configuration for dual parallel Mach–Zehnder modulator based linear microwave photonic link.
