Contribution to the development of sensors based on lossy mode resonances in planar waveguide configuration

Abstract

This thesis work shows the study and design of sensors based on the phenomenon of lossy mode resonance in a planar waveguide configuration, which is a complement to the usual platform, optical fiber. Its advantages are the simplicity of use and the robustness of the devices developed. In this sense, it has been designed, based on the deposition of copper oxide (CuO) as a resonance generating material, humidity and respiration sensors, and based on the deposition of tungsten oxide (WO3), sensors for refractive index and organic compounds such as ethanol, methanol and acetone.
