A photonics system for baseband-free arbitrary-phase-coded microwave waveform pulse (APCMWP) generation is proposed and demonstrated. The proposed system realizes the generation of APCMWP, and further solves the baseband components problem in the pulsed process. The system uses a polarization-multiplexing dual-drive Mach–Zehnder modulator (PM-DMZM) and an optical band pass filter (OBPF) to obtain a polarization-multiplexed single-sideband modulated (SSBM) optical signal with carrier intensity-phase modulation, then uses a balanced photodetector (BPD) to properly detect the polarization-multiplexed SSBM optical signal, APCMWP with baseband components suppression can be easily generated. A detailed theoretical analysis and a proof-of-concept experiment are provided. The generations of 1.2-GBaud 9.6-GHz and 2-GBaud 12-GHz baseband-free APCMWP are verified.

无基带任意相位编码的微波波形脉冲的光子产生

提出并证明了一种用于无基带任意相位编码微波波形脉冲（APCMWP）生成的光子学系统。所提出的系统实现了APCMWP的生成，并进一步解决了脉冲过程中的基带分量问题。该系统使用偏振复用双驱动马赫曾德尔调制器（PM-DMZM）和光带通滤波器（OBPF）来获得带有载波强度相位调制的偏振复用单边带调制（SSBM）光信号，然后使用平衡光电检测器（BPD）正确检测偏振复用的SSBM光信号，可以轻松生成具有基带分量抑制功能的APCMWP。提供了详细的理论分析和概念验证实验。1.2 GBaud的世代9。
