Fig. 2

Calculated transmittance of s- and p- polarized light as function of in-plane component of the wave vector and photon energy through Bragg mirror on sinusoidal profiled gold film with a thickness of 40 nm into GaAs substrate for various numbers of layer pairs (n 1 and n 2) in Bragg mirror: a one b two, and c three. The profiling period of metal film is 700 nm and depth is 50 nm. The lines correspond to “ −1” diffraction order for s- (dashed lines) and p- (dash-dotted lines) guided modes and SPP (solid lines). Red lines correspond to the dispersion of SPP for “ −1” diffraction order in the case of flat interface between gold and uniform dielectric with refractive index n 1
