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.
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.
The Institute for Photonic Integration (IPI) and the Center for Wireless Technology (CWTe) jointly organize a symposium on April, 18th, for the opening of the Advanced Photonics Lab for Ultrafast Spectroscopy, Nanophotonics and THz Imaging.Download the program here.
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…
Sara Senoris Puentes has joined the group Surface Photonics to complete a PhD. Sara has obtained her bachelor degree at the University Complutense of Madrid (Spain) and her master at the University Autonoma of Madrid. We welcome Sara to the group.
Dr, Shunsuke Murai, assistant professor at Kyoto University, will join the Surface Photonics group during 2019 for a research sabbatical. Dr. Murai’s scientific interest is on the relationship between optical properties and the structure of matter at a mesoscopic scale. We welcome Shunsuke to the group.
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…
Our proposal NanoLEDs: bringing nanophotonics into solid-state lighting, submitted together with AMOLF and Lumileds, has been granted in the High-Tech Systems and Materials call of NWO. In this project, we will quantitatively study the implementation of nanostructured surfaces designed to interact optimally with the emission of LEDs to boost blue light emission and white light…
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…
