We propose and analyze a prototype of a 60 GHz millimeter-wave (mm-wave) generator. In the scheme, two lasers with a 70 GHz frequency interval serve as sources. Then a frequency-quadrupling feed-forward modulation technique is employed to generate two phase correlated sidebands with a 60 GHz interval. The desired sidebands can be selected by using standard optical interleavers. In our work, a 60 GHz mm-wave signal free of phase noise can be achieved. The employed technique can also be extended to frequency 8-tupling.
我们提出并分析了一个 60GHz 毫米波（mm-wave）发生器的原型。在该方案中，两个频率间隔为 70GHz 的激光器用作光源。然后采用四倍频前馈调制技术产生具有 60GHz 间隔的两个相位相关边带。通过使用标准光分插复用器可以选择所需的边带。在我们的工作中，可以实现无相位噪声的 60GHzmm 波信号。所采用的技术也可以扩展到 8 倍频。
