Plasmon-Waveguide Resonances with Enhanced Figure of Merit and Their Potential for Anisotropic Biosensing in the Near Infrared Region

Figure 2

(a) Dispersion map of the TM polarized modes showing the branches of the different excited modes (see details in the text); (b) dispersion map of the TE polarized modes. The dashed red line in both panels shows the critical angle curve which originates from the prism dispersion in the interrogated spectral range.
