Figure 3. Simulated angle resolved reflection spectra with various periods.

Figure 3

The simulated angle resolved reflection spectra contour plots at periods P = 140 (a), P = 180 (b), P = 220 (c), and P = 260 nm (d). The green dash lines in all four figures indicate metal-insulator-metal Fabry-Perot (MIMFP) cavity mode, whereas the red dash lines refer to the grating assisted surface plasmon (GASP) modes whose dispersion is dependent on the grating period. The crossing between MIMFP and GASP when P = 220 and 260 nm indicates coupling between the two modes. The green dash line in (a) refers to the dispersion of odd mode defined in Figure 5(c). (e) The simulated angular absorption maxima in terms of various period from 140, 180, 220, and 260 nm.
