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…
Active tuning of highly anisotropic phonon polaritons in van der Waals crystal slabs by gated graphene
Gonzalo Álvarez-Pérez, Arturo González-Morán, Nathaniel Capote-Robayna +5
Phonon polaritons (PhPs) -- lattice vibrations coupled to electromagnetic fields -- in highly anisotropic media display a plethora of intriguing optical phenomena (including ray-li…
Real-space nanoimaging of THz polaritons in the topological insulator Bi2Se3
Shu Chen, Andrei Bylinkin, Zhengtianye Wang +6
Plasmon polaritons in topological insulators attract attention from a fundamental perspective and for potential THz photonic applications. Although polaritons have been observed by…
Focusing of in-plane hyperbolic polaritons in van der Waals crystals with tailored infrared nanoantennas
Javier Martín-Sánchez, Jiahua Duan, Javier Taboada-Gutiérrez +9
Phonon polaritons (PhPs),light coupled to lattice vibrations,with in-plane hyperbolic dispersion exhibit ray-like propagation with large wavevectors and enhanced density of optical…
Planar nano-optics in anisotropic media: anomalous refraction and diffraction-free lensing of highly confined polaritons
J. Duan, G. Álvarez-Pérez, A. I. F. Tresguerres-Mata +13
As one of the most fundamental optical phenomena, refraction between isotropic media is characterized by light bending towards the normal to the boundary when passing from a low- t…
