Abstract

We experimentally detect high-refractive-index media using a surface plasmon resonance (SPR) sensor with a diffraction grating. In this study, we used the rigorous coupled-wave analysis method to simulate the dependence of the reflectance on an incident angle for media with refractive index values up to 1.700. In the experiment, a medium (n = 1.660-1.700) was successfully detected using this grating. Under the conditions of the grating (period: 600 nm, Au thickness: 40 nm) using a red laser (: 635 nm), the extraordinary transmission enabled by SPR is occurred at the interface between Au and a medium. We concluded that this method can be applied to sensors that detect high-refractive-index media.
