Bernardo Dias joined as a Ph.D. candidate. Welcome!

Bernardo will be working on analog optical image processing with 2D quantum materials.


Nonlocal metasurface for circularly polarized light detection

In our recent paper in Optica we demonstrate a metasurface photodetector that selectively absorbs one circular polarization state while the other is fully transmitted. Check out the details to unravel the subtle physics of light scattering by engineered dislocations in semiconductor nanowires!

For more details, read our paper in Optica.


Johanna Grönqvist joined us as a PostDoc researcher. Welcome!

Johanna will be working in a joint project between the Van Wezel Lab and the Van de Groep Lab.


Tutorial: Exciton resonance tuning for atomically-thin optics

Check out our new tutorial article in Journal of Applied Physics: a didactical introduction to metasurface and exciton physics, a comprehensive overview of excitonic materials, combined with a perspective on excitonic metasurfaces! The article is featured by the editor.

For more details, read our paper in the Journal of Applied Physics.


Optofluidics for dynamic optical metasurfaces

Check out our recent paper in Nature Nanotechnology where we combine microfluidics with nanophotonic metasurfaces to realize a comprehensive platform of optofluidics to achieve dynamic control of light fields!

For more details, read our paper in Nature Nanotechnology.


Article in Nederlands Tijdschrift voor Natuurkunde published by van de Groep in collaboration with prof. Marcel Vonk

In this populair science magazine (in Dutch), we explain how a lens with a nanoscale thickness can be turned on/off at will using quantum materials!

See this link for the article.


Exciton resonance tuning of an atomically thin lens published in Nature Photonics

In our latest Nature Photonics paper we demonstrate how exciton resonances in monolayer 2D semiconductor can be used to realise large-area atomically-thin lenses with a tuneable intensity in the focus!
