Fluorescence enhancement in topologically optimized gallium phosphide all-dielectric nanoantennas
Cynthia Vidal, Benjamin Tilmann, Sunny Tiwari +4
Nanoantennas capable of large fluorescence enhancement with minimal absorption are crucial for future optical technologies from single-photon sources to biosensing. Efficient diele…
Nonlinear dielectric epsilon near-zero hybrid nanogap antennas
Romain Tirole, Benjamin Tilmann, Leonardo de S. Menezes +3
High-index Mie-resonant dielectric nanostructures provide a new framework to manipulate light at the nanoscale. In particular their local field confinement together with their inhe…
Radiative suppression of exciton-exciton annihilation in a two-dimensional semiconductor
Luca Sortino, Merve Gülmüs, Benjamin Tilmann +2
Two-dimensional (2D) semiconductors possess strongly bound excitons, opening novel opportunities for engineering light-matter interaction at the nanoscale. However, their in-plane…
High-Q nanophotonics over the full visible spectrum enabled by hexagonal boron nitride metasurfaces
Lucca Kühner, Luca Sortino, Benjamin Tilmann +5
All-dielectric optical metasurfaces with high quality (Q) factors have so far been hampered by the lack of simultaneously lossless and high refractive index (RI) materials over the…
Double-slit time diffraction at optical frequencies
Romain Tirole, Stefano Vezzoli, Emanuele Galiffi +6
The wave nature of light is revealed by diffraction from physical structures. We report a time-domain version of the classic Young's double-slit experiment: a beam of light twice g…
Saturable time-varying mirror based on an ENZ material
Romain Tirole, Emanuele Galiffi, Jakub Dranczewski +9
We report a switchable time-varying mirror, composed of an ITO-Au stack, which can be efficiently modulated in time with over a ten-fold increase in reflectivity, with a change of…
