Ammonia Gas Optical Sensor Based on Lossy Mode Resonances

This letter presents the fabrication and characterization of an ammonia (NH 3 ) gas optical sensor based on lossy mode resonances (LMRs). A chromium (III) oxide (Cr 2 O 3 ) thin film deposited onto a planar waveguide was used as LMR supporting coating. The obtained LMR shows a maximum attenuation wa...
