Author Affiliations +
The aim of this work is to highlight the possibility of local non-intrusive temperature measurements at the interface between a metallic surface and a fluid by analyzing the plasmon resonance on a periodically micro-structured surface. A change in the temperature of the sample surface induces a modification of the local refractive index leading to a shift of the surface plasmon resonance frequency due to interactions between the evanescent electric field and the close environment of the surface. The metallic gratings developed in this study enable a direct excitation of a plasmonic wave, which, in turn, lead to a high sensibility of the local temperature measurement with a very compact and simple device.
