我们通过实验证明了一种简单而稳健的方法，无需射频信号发生器 (SG) 即可实现窄线宽光学频率梳 (OFC)。我们的方法比以前的方法需要更少的射频元件。对于环路载波包络偏移频率信号，我们的方法在积分带宽从 1 Hz 到 5 MHz 时，阿伦偏差和积分 RMS 相位噪声分别为 3.3×10−16/τ 和 0.35 rad，其中 τ 是平均时间。当 RF SG 稳定性成为提高 OFC 稳定性的瓶颈时，我们的方法可能会变得非常有用。
We have experimentally demonstrated a simple and robust method for achieving a narrow-linewidth optical frequency comb (OFC) without an RF signal generator (SG). Our method requires fewer RF components than previous methods. The Allan deviation and integrated RMS phase noise with our method for the in-loop carrier-envelope-offset-frequency signal are 3.3×10−16/τ and 0.35 rad at an integration bandwidth from 1 Hz to 5 MHz, respectively, where τ is the averaging time. Our method could become very useful when RF SG stability becomes a bottleneck to improving OFC stability.
