Harnessing Evanescent Wave Interaction for Enhanced Optical NO2 Detection with Carbon Nanotube-Coated Side-Polished Fiber
arXiv:2601.03071v4 Announce Type: replace Abstract: Gas monitoring systems based on side-polished optical fibers (SPFs) coated with functional nanomaterials are gaining growing attention for their diverse applications. The response of these sensors is commonly interpreted in terms of absorption modulation of the sensing layer. Here we demonstrate that, in such systems, gas-induced reshaping of the guided optical mode can dominate the transduction mechanism and even reverse the sign of the...
