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…
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…
Revealing mode formation in quasi-bound states in the continuum metasurfaces via near-field optical microscopy
Thorsten Gölz, Enrico Baù, Andreas Aigner +5
Photonic metasurfaces offer exceptional control over light at the nanoscale, facilitating applications spanning from biosensing, and nonlinear optics to photocatalysis. Many metasu…
Nanoscale mechanical manipulation of ultrathin SiN membranes enabling infrared near-field microscopy of liquid-immersed samples
Enrico Baù, Thorsten Gölz, Martin Benoit +2
Scattering scanning near-field optical microscopy (s-SNOM) is a powerful technique for mid-infrared spectroscopy at nanometer length scales. By investigating objects in aqueous env…
