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…
