Abstract

We demonstrate ultra-sensitive gas detection with remarkable long-term stability using low-coherence photothermal interferometry. With a 10-cm-long hollow-core fiber, we achieve sub-ppb level acetylene detection with stability of ±0.038%, which outperforms the state-of-the-art fiber gas sensors.
