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 optical response. Using SPFs functionalized with single-walled carbon nanotube (SWCNT) thin films, we observe a pronounced polarization- and film thickness-de","authors_text":"Albert G. Nasibulin, Aliya R.
