Strong light-matter interactions in hybrid polaritonic systems
Ben Johns, Andrea Schirato, Federico Toffoletti +12
Strong light-matter coupling gives rise to polaritons - hybrid excitations whose mixed photonic and matter character enables control over optical, electronic and chemical propertie…
Improving conditional generative adversarial networks for inverse design of plasmonic structures
Petter Persson, Nils Henriksson, Nicolò Maccaferri
Deep learning has emerged as a key tool for designing nanophotonic structures that manipulate light at sub-wavelength scales. We investigate how to inversely design plasmonic nanos…
Polarization conversion using hybrid near-zero and high-index metamaterials
Ben Johns, Hannes Kempf, Lakshmi Das +2
Near-zero-refractive index materials display unique optical properties such as perfect transmission through distorted waveguides, cloaking, and inhibited diffraction. Compared to c…
Multipolar Decomposition of Magnetic Circular Dichroism in Arbitrarily Shaped Magneto-Dielectric Scatterers
Jhon James Hernández-Sarria, João Paulo Silva Dias, Luciano Leonel Mendes +3
Multipole expansion methods have been primarily used for analyzing the electromagnetic scattering from non-magnetic isotropic dielectric scatterers, and studies about the scatterin…
Probing macroscopic temperature changes with non-radiative processes in hyperbolic meta-antennas
Nils Henriksson, Alessio Gabbani, Gaia Petrucci +3
Multilayered metal-dielectric nanostructures display both strong plasmonic behavior and hyperbolic optical dispersion. The latter is responsible for the appearance of two separated…
Generation of ultrashort light pulses carrying orbital angular momentum using a vortex plate retarder-based approach
Tlek Tapani, Haifeng Lin, Aitor De Andres +3
We use a vortex retarder-based approach to generate few optical cycles light pulses carrying orbital angular momentum (known also as twisted light or optical vortex) from a Yb:KGW…
Plasmonic Photochemistry as a Tool to Prepare Metallic Nanopores with Controlled Diameter
German Lanzavecchia, Joel Kuttruff, Andrea Doricchi +8
We show that plasmonic solid-state nanopores with tunable hole diameter can be prepared via a photocatalytic effect resulting from the enhanced electromagnetic field inside a metal…
Magnetoplasmonics: current challenges and future opportunities
Nicolò Maccaferri, Alessio Gabbani, Francesco Pineider +3
Plasmonics represents a unique approach to confine and enhance electromagnetic radiation well below the diffraction limit, bringing a huge potential for novel applications, for ins…
Advances in ultrafast plasmonics
Alemayehu Nana Koya, Marco Romanelli, Joel Kuttruff +22
In the past twenty years, we have reached a broad understanding of many light-driven phenomena in nanoscale systems. The temporal dynamics of the excited states are instead quite c…
Magnetic Circular Dichroism in Hyperbolic Metamaterial Nanoparticles
Joel Kuttruff, Alessio Gabbani, Gaia Petrucci +10
The optical properties of some nanomaterials can be controlled by an external magnetic field, providing active functionalities for a wide range of applications, from single-molecul…
