(a) SEM Micrograph of the fabricated 1D plasmonic nanograting with period of 200 nm (b) a micrograph showing the integrated plasmonic nanograting glued on top of the prism (c) Schematic drawing of the experimental SPR setup. A TM polarized beam from the broadband source is incident on the sample and the reflectivity is measured by the fiber-coupled spectrometer (d) Experimentally measured reflection spectra of the samples without (blue) and with (red) the plasmonic grating at incident angles of ~46.2° and ~83°, respectively.
