Self-Referenced Plasmon Waveguide Resonance Sensor Using Different Waveguide Modes

Figure 2

((a), (b), and (c)) The figure of merit, surface combined sensitivity factor (CSF), and bulk CSF plotted against the gold film thickness. The silica films have the thickness of 1000 nm. The refractive indices of the prism, gold, silica, and water are 1.515, 0.133 + 3.654, 1.46, and 1.33, respectively. The incident wavelength is 632.8 nm. (d) The angular reflectance spectra with the gold film of 55 nm and 60 nm.
