Orbital Angular Momentum Locking via Bound States in the Continuum
Enrico Baù, Connor Heimig, Jonas Biechteler +6
Optical vortices are electromagnetic fields twisting around a phase singularity, resulting in quantized orbital angular momentum (OAM). When such vortices are formed by evanescent…
Phonon-polaritonic skyrmions: Transition from bubble- to Néel-type
Florian Mangold, Enrico Baù, Lin Nan +6
Optical skyrmions are members of the emerging topological branch of solid-state physics and photonics, allowing for control over topological light textures through light-matter int…
Accessible, All-Polymer Metasurfaces: Low Effort, High Quality Factor
Michael Hirler, Alexander A. Antonov, Enrico Baù +4
Optical metasurfaces supporting resonances with high quality factors offer an outstanding platform for applications such as non-linear optics, light guiding, lasing, sensing, light…
Spatially Encoded Polaritonic Ultra-Strong Coupling in Gradient Metasurfaces with Epsilon-Near-Zero Modes
Enrico Bau, Andreas Aigner, Jonas Biechteler +4
We introduce a platform to achieve ultra-strong coupling (USC) between light and matter using widely available materials. USC is a light-matter interaction regime characterized by…
Interface second harmonic generation enhancement in hetero-bilayer van der Waals nanoantennas
Andrea Tognazzi, Paolo Franceschini, Jonas Biechteler +5
Layered van der Waals (vdW) materials have emerged as a promising platform for nanophotonics due to large refractive indexes and giant optical anisotropy. Unlike conventional diele…
