This work presents a first approach to the utilization of Lossy Mode Resonance (LMR)
based optical fiber sensors for gas detection. The optical sensor is based on a SnO2 thin-film
fabricated onto the core of cladding removed multimode fibers (MMF). The time response of the
device to four different gases (NH3, NO, CO2 and O2) was monitored obtaining the best sensitivity
for NO whereas the response to NH3 revealed the best repeatability.
