Title (EN) PLASMONIC LASER AND ITS FABRICATION PROCESS
(FR) LASER PLASMONIQUE ET SON PROCEDE DE FABRICATION.
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.
(FR) Laser plasmonique comprenant : une nanostructure métallique (RP) supportant une pluralité de modes plasmoniques; et - un milieu à gain (MG) présentant un gain optique à la fréquence d'oscillation d'au moins un dit mode plasmonique, couplé en champ optique proche avec ladite nanostructure; caractérisé en ce que ledit milieu à gain est structuré à l'échelle nanométrique de manière à présenter une forme qui épouse la distribution spatiale d'intensité d'un dit mode plasmonique, à la fréquence duquel ledit milieu à gain présente un gain optique. Procédé de fabrication d'un tel laser plasmonique.
