Nonlinear Excitation of Ideal Anapoles
Radoslaw Kolkowski, Matti Kaivola, Andriy Shevchenko
Optical anapoles have attracted significant interest as a promising platform for enhancing light-matter interactions at the nanoscale. An ideal anapole is a localized excitation of…
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…
Minireview on Disordered Optical Metasurfaces
P. Lalanne, A. Dmitriev, C. Rockstuhl +2
The use of coherent wave phenomena to enhance device performance is a cornerstone of modern optics. In juxtaposition to (locally) periodic metasurfaces, their disordered counterpar…
Spontaneous symmetry breaking in plasmon lattice lasers
Nelson de Gaay Fortman, Radoslaw Kolkowski, Debapriya Pal +3
Spontaneous symmetry breaking (SSB) is key for our understanding of phase transitions and the spontaneous emergence of order. Photonics provide versatile systems to study SSB. In t…
Enabling infinite factors in absorbing optical systems
Radoslaw Kolkowski, Andriy Shevchenko
Resonant optical systems have widespread applications in science and technology. However, their quality () factors can be significantly deteriorated, if some of their parts exhi…
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…
Long Range Coupling between Metallic Nanocavities
Adi Salomon, Yehiam Prior, Michael Fedoruk +3
When two or more metallic nanoparticles are in close proximity, their plasmonic modes may interact through the near field, leading to additional resonances of the coupled system or…
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…
Shape and Size Resonances in Second Harmonic Generation from Plasmonic Nano-Cavities
Adi Salomon, Marcin Zielinski, Radoslaw Kolkowski +2
The nonlinear response of sub wavelength nano-cavities in thin metal films is investigated. We report the resonant dependence of the Second Harmonic Generation by individual triang…
