Abstract

A single-nanoparticle plasmon laser with ultratight optical confinement in all three dimensions is a long-cherished but yet to be realized goal. Here we propose an experimentally realizable plasmon laser using a single nanorod. We show that, by harnessing a Au-nanorod cavity with a large gain from a Purcell-enhanced stimulated emission rate and greatly suppressed high-order mode dissipation, it is possible to implement a dipole-mode plasmon laser with accessible material parameters. Our approach may lead to a real single-nanoparticle plasmon laser with three-dimensional ultraconfinement and offers an opportunity to explore and utilize the enhanced light-matter interaction at a lower dimension.
