    Abstract

    Propagation of surface plasmons on gold in the range 2.8-3.5 eV over 0.1-1.6 mu m distances was characterized by cathodoluminescence spectroscopy. Surface plasmons were excited by an electron beam near a grating milled in the gold. The spectra of outcoupled radiation reveal increasingly strong propagation losses as surface plasmon energy increases above 2.8 eV, but little effect in the range 1.6-2.8 eV. These results are in partial agreement with theoretical expectations. (C) 2008 Optical Society of America
