Abstract
Highly localized, laser-excited optical modes of silver colloid fractal clusters were observed using photon scanning tunneling microscopy. The spatial distribution of the modes shows the frequency and polarization selectivity suggested by numerical simulations. The results verify the main concepts of the recently developed resonant optical theory of fractal objects.Keywords
