Abstract:
We have demonstrated that double-tuned absorptions have the characteristics of forming a flat peak in an attenuated-total-reflection structure containing a metal-clad dielectric-film waveguide with a low-refractive-index buffer layer. The double-tuned characteristics occur because the guided mode in the film waveguide couples to the surface plasma mode at the metal-buffer layer interface.
