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…
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…
MoOCl as a Hyperbolic Planar Platform for Nanooptics at Telecom Frequencies
Haozhe Tong, Clara Clemente-Marcuello, Kirill V. Voronin +2
On-chip optoelectronics is fundamental to modern telecommunication, yet the diffraction limit of light remains a major obstacle to the extreme miniaturization of photonic integrate…
Launching of Visible-Range Hyperbolic Polaritons by Gold Nanoantennas in a natural van der Waals crystal
Clara Clemente-Marcuello, Haozhe Tong, Kirill V. Voronin +2
Anisotropic van der Waals materials provide a powerful platform for nanoscale optoelectronics, enabling strong lightmatter interaction and deep electromagnetic field confinement…
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…
Bloch phonon-polaritons with anomalous dispersion in polaritonic Fourier crystals
Sergey G. Menabde, Yongjun Lim, Alexey Y. Nikitin +5
The recently suggested concept of a polaritonic Fourier crystal (PFC) is based on a harmonically-corrugated mirror substrate for a thin pristine polaritonic crystal layer. The prop…
