Metasurface lasers programmed by optical pump patterns
Nelson de Gaay Fortman, Radoslaw Kolkowski, Nick Feldman +2
Metasurface lasers offer unprecedented control over light emission, yet their spatial and modal characteristics are typically fixed post-fabrication. Here, we introduce a reconfigu…
Plasmonic Metasurfaces with Structural Chirality and Pseudo-Chirality for Enhanced Circular Dichroism and Enantiomeric Recognition
Giovanna Palermo, Bryan Guilcapi, Radoslaw Kolkowski +6
We present the design and optical characterization of a plasmonic metasurface engineered to exhibit strong polarization anisotropy under both linearly and circularly polarized ligh…
Universal power law decay in the dynamic hysteresis of an optical cavity with non-instantaneous photon-photon interactions
Z. Geng, K. J. H. Peters, A. A. P. Trichet +4
We investigate, experimentally and theoretically, the dynamic optical hysteresis of a coherently driven cavity with non-instantaneous photon-photon interactions. By scanning the fr…
From individual to strongly coupled metallic nanocavities
Adi Salomon, Yehiam Prior, Radoslaw Kolkowski +1
Localized plasmonic modes of metallic nanoparticles may hybridize like those of atoms forming a molecule. However, the rapid decay of the plasmonic fields outside the metal severel…
