Abstract
Highly-doped graphene has emerged as a promising material platform for nonlinear plasmonics that combines long-lived and electrically-tunable plasmons with an intensely anharmonic response to light originating from its unique electronic band structure. Here the appealing nonlinear optical properties of graphene are demonstrated to persist in its nanostructured form, even down to molecular sizes, where plasmons supported by significantly fewer electrons than those of noble metal nanoparticles are found to exhibit intense harmonic generation and extraordinary thermo-optical switching capabilities. Nonlinear plasmons in graphene nanostructures are further shown to undergo strong coupling with nearby quantum emitters or amongst themselves, potentially enabling nonlinear interactions of plasmons on the single-photon level.
