Abstract: It remains a major challenge to prepare a temperature or humidity optical fiber sensor with a simple structure, low cost and high sensitivity. In this work, a Mach-Zehnder interferometer ...

Moisture-swing direct air capture (DAC), which uses changes in humidity to catch carbon, will be central to global strategies to combat climate change, but its scalability has been limited due to the ...

Abstract: A high-sensitivity fiber-optic microcavity relative humidity (RH) sensor with a silicon-based sulfide thin ... The microcavity is constructed on the end surface of a single-mode fiber (SMF) ...
