Limits to strong coupling in 2D semiconductors

Our manuscript “Limits to Strong Coupling of Excitons in Multilayer WS2 with Collective Plasmonic Resonances” has been accepted for publication in ACS-Photonics. In this manuscript, we demonstrate experimentally and describe theoretically that strong light-matter coupling in of optical modes with excitons in 2D semiconductors is limited by dielectric screening as the thickness of the semiconductor…

Enhanced quality factors of surface lattice resonances in plasmonic arrays of nanoparticles published in Advanced Optical Materials

We investigate experimentally and numerically two-dimensional arrays of silver nanoparticles and show how the Q-factor of collective plasmonic resonances critically depends on the quality of the metal film, the detuning between diffraction orders and localized resonances and the absorption of adhesive layer used between the substrate and the metallic nanoparticles. These silver nanoparticle arrays can…

Nonlinear Emission of Molecular Ensembles Strongly Coupled to Plasmonic Lattices with Structural Imperfections published in Physical Review Letters

We demonstrate nonlinear emission from molecular layers strongly coupled to extended light fields in arrays of plasmonic nanoparticles in the presence of structural imperfections. In contrast to recent observations of exciton-polariton lasing and condensation in organic systems, photonic modes play a minor role at the emission frequency in our system, and this emission has an…

Accepted manuscript on a novel method to measure time-resolved THz photoconductivity in the near-field

In this manuscript, we show proof-of-concept measurements on a GaAs film that was excited though a total internal reflection geometry. With this technique, we can obtain the photo-excited carrier dynamics and the THz photo-conductivity with a spatial resolution well below the THz diffraction limit. The manuscript entitled “Time-resolved terahertz time-domain near-field microscopy” has been published…

Special topic “Dielectric Nanoresonators and Metamaterials” of the Journal of Applied Physics open for submission until Dec. 31st

High-refractive-index (HRI) dielectric nanostructures, and in particular semiconductors, are attracting great attention in Optics and Photonics nowadays for their low dissipative losses, which hold promise of high-efficiency devices, and unique optical properties, exhibiting strong magnetic-like optical resonances and associated scattering directionality, which renders them as excellent nanoantennas. Thereby a wealth of new or enhanced fundamental…
