Abstract:
The dispersion behavior of surface plasmons on silver gratings in the center of the first Brillouin zone is determined by measurements of the reflected light as a function of amplitude and of the profile of the gratings. We studied the dispersion relation of sinusoidal gratings, rectangular gratings, and incoherent gratings. We found a strict relationship between the profile of the grating and the dispersion relation of the surface plasmons. Our experiments showed at small amplitudes a crossing of the dispersion branches without a gap. For higher amplitudes a frequency or a momentum gap occurred depending on whether the profile had higher Fourier components or not. The experimental results are in accordance with numerical simulations.
