Shaping Near Fields of Photonic Modes into Topological Textures
Jonas Biechteler, Michael Hirler, Connor Heimig +5
Topological textures of light, such as optical vortices and skyrmions, are attractive for high-density information encoding and light-matter interactions. In the near field, topolo…
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…
Transient infrared nanoscopy resolves the millisecond photoswitching dynamics of single lipid vesicles in water
Thorsten Gölz, Enrico Baù, Jinhua Zhang +6
Understanding the biophysical and biochemical properties of molecular nanocarriers under physiological conditions and with minimal interference is crucial for advancing nanomedicin…
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…
Origin of optical nonlinearity in plasmonic semiconductor nanostructures
Andrea Rossetti, Huatian Hu, Tommaso Venanzi +15
The development of nanoscale nonlinear elements in photonic integrated circuits is hindered by the physical limits to the nonlinear optical response of dielectrics, which requires…
