论文摘要
频率梳吸收光谱与低噪声相结合，快速同伴测量为超敏感吸收测量提供了工具箱。将这些方案集成到光子平台上，以使它们更接近实际应用是具有挑战性的。在这里，我们提出了一个可以在光子平台上轻松适应的方案。我们表明，每个频率梳子牙齿都可以独立采样，可以定制梳子的跨度，并且我们的方法不需要仔细地对准梳子中心与任何吸收曲线。这允许完全重建不对称的吸收曲线，而无需其他组件。
Frequency comb absorption spectroscopy combined with low-noise, fast homodyne measurements provide a toolbox for ultra-sensitive absorption measurements. Integrating these schemes on photonic platforms to bring them closer to practical applications is challenging. Here, we propose a scheme that can be readily adapted on a photonic platform. We show that each frequency comb tooth can independently sampled, the span of the comb can be tailored, and that our method does not require a careful alignment of the comb centre with any absorption profiles. This allows an asymmetric absorption profile to be reconstructed in full without requiring additional components.
