Abstract

Plasmon nanofocusing is a phenomenon that creates a localized strong light field at the apex of a tapered metallic structure by propagating plasmons on the metallic taper toward the apex with compressing light energy. One of interesting properties of plasmon nanofocusing is that it can be excited over a broad wavelength range. In this talk, focusing on broadband property of plasmon nanofocusing, we introduce our recent works from fundamental studies to advanced applications. We also discuss potentials of the broadband nanolight source created by plasmon nanofocusing for future applications.
