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…
Highly confined incident-angle-robust surface phonon polariton bound states in the continuum metasurfaces
Lin Nan, Andrea Mancini, Thomas Weber +4
Squeezing light into subwavelength dimensions is vital for on-chip integration of photonic technologies. One approach to overcome the diffraction limit is coupling light to materia…
Multiplication of the orbital angular momentum of phonon polaritons via sublinear dispersion
Andrea Mancini, Lin Nan, Rodrigo Berté +3
Optical vortices (OVs) promise to greatly enhance optical information capacity via orbital angular momentum (OAM) multiplexing. The need for on-chip integration of OAM technologies…
Second harmonic generation in germanium quantum wells for nonlinear silicon photonics
Jacopo Frigerio, Chiara Ciano, Joel Kuttruff +12
Second-harmonic generation (SHG) is a direct measure of the strength of second-order nonlinear optical effects, which also include frequency mixing and parametric oscillations. Nat…
Pump-probe Spectroscopy Study of Ultrafast Temperature Dynamics in Nanoporous Gold
Michele Ortolani, Andrea Mancini, Arne Budweg +3
We explore the influence of the nanoporous structure on the thermal relaxation of electrons and holes excited by ultrashort laser pulses ( fs) in thin gold films. Plasmon d…
Surface Thermal Gradients Activated by Enhanced Molecular Absorption in Mid-infrared Vertical Antenna Arrays
Andrea Mancini, Valeria Giliberti, Alessandro Alabastri +4
We investigate local heat generation by molecules at the apex of polymer-embedded vertical antennas excited at resonant mid-infrared wavelengths, exploiting the surface enhanced in…
