We present a novel and simple scheme to generate high‐quality V‐band (50‐75GHz) vector millimeter‐wave (mm‐wave) based on dual‐parallel Mach‐Zehnder modulators (DPMZM) without resorting to adopting optical filter and precoding. By controlling the bias voltage of the DPMZM and phase shift between the two beams of each sub‐MZM, we can obtain a higher frequency optical vector mm‐wave signal. We have discussed the feasibility of this scheme and achieved the generation of V‐band vector mm‐wave with the frequency at 65 GHz by simulation. According to bit‐error‐ratio curves, we can demonstrate the validity of the presented scheme to generate V‐band QPSK/16QAM vector mm‐wave signal.

通过双并行Mach-Zehnder调制器实现的V波段矢量毫米波信号生成，无需预编码和光学滤波器

我们提出了一种新颖且简单的方案，该方案可基于双并行马赫曾德尔调制器（DPMZM）生成高质量的V波段（50-75GHz）矢量毫米波（mmwave），而无需采用光学滤波器和预编码。通过控制DPMZM的偏置电压和每个子MZM的两个光束之间的相移，我们可以获得更高频率的光矢量毫米波信号。我们已经讨论了该方案的可行性，并通过仿真实现了在65 GHz频率下生成V波段矢量毫米波。根据误码率曲线，我们可以证明所提方案生成V波段QPSK / 16QAM矢量毫米波信号的有效性。
