Microfiber evanescent-field photothermal gas detection using acoustic-induced mode-dependent frequency shift

open access: yesNanophotonics, 2023
In this study, we experimentally showcase the microfiber evanescent-field photothermal gas detection by exploiting all-fiber MHz-level frequency shift scheme. Based on the acousto-optic interaction effect, the low-frequency shifts of 0.9 MHz and 1.83 MHz
