Wave-mixing cathodoluminescence microscopy of low-frequency excitations
Leila Prelat, Eduardo J. C. Dias, F. Javier García de Abajo
Nonlinear optical phenomena such as parametric amplification and frequency conversion are typically driven by external optical fields. Free electrons can also act as electromagneti…
Free-electron coupling to surface polaritons mediated by small scatterers
Leila Prelat, Eduardo J. C. Dias, F. Javier García de Abajo
The ability of surface polaritons (SPs) to enhance and manipulate light fields down to deep-subwavelength length scales enables applications in optical sensing and nonlinear optics…
Terahertz lasing conditions of radiative and nonradiative propagating plasmon modes in graphene-coated cylinders
Leila Prelat, Nicolas Passarelli, Raul Bustos-Marun +1
There is increasing interest in filling the gap of miniaturized terahertz/mid-infrared radiation sources and, particularly, in incorporating these sources into micro/nanophotonic c…
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…
