Spaser and Optical Amplification Conditions in Graphene-Coated Active Wires
Leila Prelat, Mauro Cuevas, Nicolás Passarelli +2
This work analyzes the optical properties of a localized surface plasmon (LSP) spaser made of a dielectric active wire coated with a graphene monolayer. Our theoretical results, ob…

Theoretical Analysis of Metallic-Nanodimer Thermoplasmonics for Phototactic Nanoswimmers
Andrés I. Bertoni, Nicolás Passarelli, Raúl Bustos-Marún
We assess the potentiality of several geometries of metallic nanodimers (one of the simplest thermoplasmonic systems) as candidates for active particles (nanoswimmers) propelled an…

Lasing Conditions of Transverse Electromagnetic Modes in Metallic-Coated Micro- and Nanotubes
Nicolás Passarelli, Raúl Bustos-Marún, Ricardo Depine
In this work, we study the lasing conditions of the transverse electric (TE) modes of micro- and nanotubes coated internally with a thin metallic layer. This geometry may tackle so…
