Control of optical heating of a silicon probe using near-field energy transport by localized surface plasmons

Abstract

Optical heating in solids is fundamentally related to energy dissipation during absorption. Nevertheless, light absorption can be enhanced by excitation of optical resonances (plasmon, Mi, Fano, etc.). In this paper, we investigate the amplification of light absorption in nanostructured silicon by excitation of an optical near field in the gap between the tip of a silicon probe and a gold film.
