我们提出了一种新的方法，我们认为是产生光学毫米波信号的频率四倍使用两个级联马赫-曾德尔调制器（MZMs）。理论分析和实验验证。通过对称偏置MZM，无需任何光学滤波器或电气设备，获得了具有大于25 dB的光学谐波失真抑制比的40 GHz的高质量毫米波。此外，它也被证明是有效的，所提出的方案是不敏感的MZM的偏置漂移，这表明了相对较高的稳定性。
We propose what we believe to be a novel method to generate optical millimeter-wave signals with frequency quadrupling using two cascaded Mach-Zehnder modulators (MZMs). Both theoretical analysis and experimental demonstration are presented. By symmetrically biasing the MZMs, without any optical filters or electrical devices, a high-quality millimeter wave at 40 GHz with an optical harmonic distortion suppression ratio of more than 25 dB is obtained. Furthermore, it is also proved to be valid that the proposed scheme is insensitive to the MZM bias drift, which demonstrates a relatively higher stability.
