Microfiber evanescent-wave photothermal methane sensor with sub-ppm sensitivity

Published: August 31, 2022

We report microfiber evanescent-wave photothermal spectroscopy for trace gas detection. With a 2-cm-long silica microfiber, detection limit of 440 ppb methane is achieved with dynamic range of nearly six orders of magnitude and response time of less than 7 seconds. More information here

High-sensitivity fiber-tip photothermal gas sensor based on a 3d µ-printed fabry-pérot microcavity

Published: November 23, 2023

We report a miniature fiber-optic photothermal gas sensor based on a Fabry-Pérot microcavity directly 3D µ-printed on the end-face of a standard single-mode optical fiber. A detection limit of 0.4 parts-per-million for acetylene is demonstrated.
