Preserving the quality of atomic layers

Our publication on how to preserve the quantum efficiency of monoatomic layers of transition metal dichalcogenides (TMDs) during transfer has been accepted for publication in Advanced Optical Materials. The effects of encapsulation on the optical properties of TMD monolayers, focusing on the impact of different processing techniques and different dielectric environments have been investigated. Read…

Surface lattice resonances imaged with super-resolution microscopy

In collaboration with the group of Andrea Baldi from the Dutch Institute for Fundamental Energy Research (DIFFER), we have mapped the enhanced emission of single fluorescent molecules coupled to a plasmonic particle array using stochastic super-resolution microscopy. You can read the results here. Read also the DIFFER news item.

Diffraction enhanced transparency in a hybrid gold-graphene THz metasurface

Our manuscript Diffraction Enhanced Transparency in a Hybrid Gold-Graphene THz Metasurface published in APL Photonics. Herein, we measure the near-field in arrays of THz resonators having a transparency window. A monolayer of graphene is sufficient to suppress the transparency.

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…
