Infrared light scattering and emission from epsilon near-zero hyperbolic phonon-polaritons in two-dimensional crystals
Flavio Henrique Feres, Martin Bearzatto, Adrien Debacq +24
This work presents the near-field super-scattering and the near-field thermal emission from 2D hyperbolic crystals as general optical phenomena that link near-field nanophotonics t…
Ultra-high THz-field-confinement at LaAlO3 twin walls
Jakob Wetzel, Javier Taboada-Gutiérrez, Matthias Roeper +13
The control and steering of light at nanometre length scales is crucial for the development of both fundamental science and nanophotonic technologies. Recent advancements have been…
Free-electron laser-based extended wide-field mid-infrared photothermal imaging for biomedical and microplastic analysis
Anooj Thayyil Raveendran, Subham Adak, Artem Shydliukh +8
Wide-field mid-infrared photothermal (MIP) imaging offers rapid labelfree chemical contrast for biomedical and polymer analysis. However, its field of view (FOV) is limited by the…
Spectral tuning of hyperbolic shear polaritons in monoclinic gallium oxide via isotopic substitution
Giulia Carini, Mohit Pradhan, Elena Gelzinyte +26
Hyperbolic phonon polaritons - hybridized modes arising from the ultrastrong coupling of infrared light to strongly anisotropic lattice vibrations in uniaxial or biaxial polar crys…
Ultraconfined THz Phonon Polaritons in Hafnium Dichalcogenides
R. A. Kowalski, N. S. Mueller, G. Álvarez-Pérez +18
The confinement of electromagnetic radiation to subwavelength scales relies on strong light-matter interactions. In the infrared (IR) and terahertz (THz) spectral ranges, phonon po…
Unidirectional Ray Polaritons in Twisted Asymmetric Stacks
J. Álvarez-Cuervo, M. Obst, S. Dixit +25
The vast repository of van der Waals (vdW) materials supporting polaritons offers numerous possibilities to tailor electromagnetic waves at the nanoscale. The development of twisto…
Terahertz Twistoptics -- engineering canalized phonon polaritons
Maximilian Obst, Tobias Nörenberg, Gonzalo Álvarez-Pérez +11
The terahertz (THz) frequency range is key to study collective excitations in many crystals and organic molecules. However, due to the large wavelength of THz radiation, the local…
Germanium monosulfide as a natural platform for highly anisotropic THz polaritons
Tobias Nörenberg, Gonzalo Álvarez-Pérez, Maximilian Obst +8
Terahertz (THz) electromagnetic radiation is key to optically access collective excitations such as magnons (spins), plasmons (electrons), or phonons (atomic vibrations), thus brid…
