Abstract

In this work, the fabrication and characterization of novel humidity sensors based on Lossy Mode Resonances (LMR) is presented. Tin oxide (SnO ₂) coatings fabricated onto optical fibers are used as LMR supporting coatings. The SnO₂ based refractometers showed an average sensitivity of 6715 nm/refractive index unit (RIU) in the range 1.333-1.420 RIU. The behavior of this optical fiber device as relative humidity (RH) sensor was also tested, monitoring its response to different surrounding humidity levels. The results show a sensitivity of 0.1 nm/RH% in the range from 20% to 80% RH.
