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…
Prospects to bypass nonlocal phenomena in metals using phonon-polaritons
Jacob T. Heiden, Eduardo J. C. Dias, Minhyuk Kim +6
Electromagnetic design relies on an accurate understanding of light-matter interactions, yet often overlooks electronic length scales. Under extreme confinement, this omission can…
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…
High-harmonic generation enhancement with graphene heterostructures
Irati Alonso Calafell, Lee A. Rozema, Alessandro Trenti +9
We investigate high-harmonic generation in graphene heterostructures consisting of metallic nanoribbons separated from a graphene sheet by either a few-nanometer layer of aluminum…
Fundamental Limits to the Coupling between Light and 2D Polaritons by Small Scatterers
Eduardo J. C. Dias, F. Javier García de Abajo
Polaritonic modes in two-dimensional van der Waals materials display short in-plane wavelengths compared with light in free space. As interesting as this may look from both fundame…
Graphene Plasmons in Triangular Wedges and Grooves
P. A. D. Gonçalves, E. J. C. Dias, Sanshui Xiao +3
The ability to effectively guide electromagnetic radiation below the diffraction limit is of the utmost importance in the prospect of all-optical plasmonic circuitry. Here, we prop…
