Plasmon waveguide detector of refractive index changes in planar system

摘要

The paper presents the structure of two laboratory models of waveguide planar sensors of refractive index changes of liquids. Both systems have been designed basing on plasmon resonance along the interface between metallic layer and measured liquid. The models have been constructed basing on planar waveguides as well as on strip waveguides. The measurement results of spectral transmittance of the investigated structures have been presented as the function of refractive index of the measured liquid.
