In-plane vector-field imaging of propagating surface phonon polaritons
Richarda Niemann, Dorothée S. Mader, Gonzalo Alvarez-Pérez +9
Polariton interferometry through optical near-field microscopy has become a powerful tool in nanophotonics, enabling direct spatial access to the propagation characteristics of str…
Twistoptics in Planar Heterostructures with an Arbitrary Number of Rotated 3D Thin Layers and 2D Conductive Sheets
Christian Lanza, José Ãlvarez-Cuervo, Kirill V. Voronin +5
Twistoptics has recently emerged as a branch of nano-optics that explores light propagation in stacks of thin anisotropic layers rotated relative to one another. The concept is par…
Fast Programming of In-Plane Hyperbolic Phonon Polariton Optics Through van der Waals Crystals using the Phase-Change Material In3SbTe2
Lina Jäckering, Umberto Saldarelli, Aaron Moos +8
The high directionality of hyperbolic phonon polaritons (HPhPs) has opened radically new ways to route and steer the flow of energy at the nanoscale. However, launching HPhPs requi…
Directional strong coupling at the nanoscale between hyperbolic polaritons and organic molecules
Ana I. F. Tresguerres-Mata, Olga G. Matveeva, Christian Lanza +17
Strong coupling (SC) is a fundamental concept in physics that describes extreme interactions between light and matter. Recent experiments have demonstrated SC at the nanometer scal…
Low-loss twist-tunable in-plane anisotropic polaritonic crystals
Nathaniel Capote-Robayna, Ana I. F. Tresguerres-Mata, Aitana Tarazaga MartÃn-Luengo +4
Van der Waals (vdW) materials supporting phonon polaritons (PhPs) - light coupled to lattice vibrations - have gathered significant interest because of their intrinsic anisotropy a…
