Abstract
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.
