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.
