Reprogrammable polaritonic skyrmion and meron lattices based on the phase-change material InSbTe
Lina Jäckering, Arvid Schick, Enrico Baù +7
Optical topological quasiparticles such as skyrmions and merons consist of engineered electromagnetic fields which can be realized via the controlled interference of polaritons. Th…
Understanding inhomogeneous crystallization dynamics of phase-change materials in the vicinity of metallic nanoantennas
Luis Schüler, Lukas Conrads, Yingfan Chen +5
Optical metasurfaces composed of metallic or dielectric scatterers (meta-atoms) promise a powerful way of tailoring light-matter interactions. Phase-change materials (PCMs) are pri…
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…
Tailoring hBN's Phonon Polaritons with the Plasmonic Phase-Change Material In3SbTe2
Lina Jäckering, Aaron Moos, Lukas Conrads +8
Polaritons in van-der-Waals materials (vdWM) promise high confinement and multiple tailoring options by optical structures, e.g., resonators, launching structures and lenses. These…
