这项工作提出了一种采用频率八倍频的经济高效、连续可调且无滤波器的光学毫米波 (MMW) 信号生成方法。可以获得具有 30dB 不需要的边带抑制比的光毫米波信号。由于不需要光学滤波，因此所提出的系统可以很容易地在波分复用（WDM）系统中实现。 V 波段 60 GHz 和 W 波段 80 GHz 光毫米波信号经过实验演示。由于不需要的边带抑制比很高，因此可以观察到占空比为 50% 的 60 GHz 波形。生成的 60 GHz 信号的单边带 (SSB) 相位噪声在 10 kHz 时为 -73 dBc/Hz。所提出的系统是未来高达 320 GHz 的超高频毫米波应用的可行解决方案，使用带宽有限的 40 GHz 外部调制器。
This work proposes a cost-effective, continuously tunable and filterless optical millimeter-wave (MMW) signal generation employing frequency octupling. Optical MMW signals with 30-dB undesired sideband suppression ratios can be obtained. Since no optical filtering is required, the proposed system can be readily implemented in wavelength-division-multiplexing (WDM) systems. V-band 60-GHz and W-band 80-GHz optical MMW signals are experimentally demonstrated. Because of the high undesired sideband suppression ratio, 60-GHz waveform with 50% duty cycle is observed. The single-sideband (SSB) phase noise of the generated 60-GHz signal is -73 dBc/Hz at 10 kHz. The proposed system is a viable solution for the future ultra-high frequency MMW applications up to 320 GHz using the external modulator with a limited bandwidth of 40 GHz.
