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…
Visualization of topological shear polaritons in gypsum thin films
Pablo DÃaz-Núñez, Christian Lanza, Ziwei Wang +10
Low symmetry crystals have recently emerged as a platform for exploring novel light-matter interactions in the form of hyperbolic shear polaritons. These excitations exhibit unique…
Unidirectional Ray Polaritons in Twisted Asymmetric Stacks
J. Ãlvarez-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…
Canalization-based super-resolution imaging using a single van der Waals layer
Jiahua Duan, Aitana Tarazaga Martin-Luengo, Christian Lanza +7
Canalization is an optical phenomenon that enables unidirectional propagation of light in a natural way, i.e., without the need for predefined waveguiding designs. Predicted years…
