Abstract
(EN)
Plasmonic laser comprising: a metal nanostructure (RP) supporting a plurality of plasmon modes; and a gain medium (MG), providing optical gain at the frequency of oscillation of at least one of said plasmon modes, coupled in the optical near field with said nanostructure, characterized in that said gain medium is structured at the nanoscale so as to have a shape that closely follows the spatial intensity distribution of one of said plasmon modes, at the frequency at which said gain medium has an optical gain. Process for fabricating such a plasmonic laser.
