Transformation optics for plasmonics: from metasurfaces to excitonic strong coupling
Comptes Rendus. Physique, Volume 21 (2020) no. 4-5, pp. 389-408.

Part of the special issue: Metamaterials 1

We review the latest theoretical advances in the application of the framework of Transformation Optics for the analytical description of deeply sub-wavelength electromagnetic phenomena. First, we present a general description of the technique, together with its usual exploitation for metamaterial conception and optimization in different areas of wave physics. Next, we discuss in detail the design of plasmonic metasurfaces, including the description of singular geometries which allow for broadband absorption in ultrathin platforms. Finally, we discuss the quasi-analytical treatment of plasmon–exciton strong coupling in nanocavities at the single emitter level.

Nous passons en revue les dernières avancées dans l’application du cadre de l’optique transformationnelle pour la description analytique des phénomènes électromagnétiques en régime fortement sub-longueur d’onde. En premier lieu, nous présentons une description générale de la technique, ainsi que son exploitation usuelle dans la conception et l’optimisation des métamatériaux dans différentes disciplines de la physique des ondes. En second lieu, nous discutons en détail de la conception de métasurfaces plasmoniques, y compris la description de géométries singulières qui permettent une absorption sur une large plage de fréquences dans les plates-formes ultra-minces. Enfin, nous discutons du traitement quasi-analytique du couplage fort plasmon–exciton dans les nanocavités au niveau d’un seul émetteur.
