Amazing work by the team, lead by co-first authors Andreas Aigner and Thomas Possmayer! For a broader view on what we did also check out the @LMU_Muenchen press release:

As a central concept, we developed resonators that are geometrically asymmetric, but appear "symmetric" (in the language of symmetry-protected BICs) for light. We can break this photonic symmetry by selective ultrafast optical pumping, giving us full control over the resonances.

Proud to share that our new paper is now out in @Nature 🥳 We introduce a new mechanism for the all-optical and ultrafast control of resonances in BIC metasurfaces through temporal symmetry breaking. It's an ultrafast light switch on the nanoscale!

Check out the LMU press release about our recent paper on all-optical resonance generation in unstructured silicon films:

We developed an optimized nanofabrication approach for getting much better resonances from hBN metasurfaces 🚀 Q factors of 1000 and high modulations throughout the visible, ideal for boosting light-matter coupling. Out in Advanced Optical Materials:

This is the culmination of our efforts on metasurfaces composed of only a single vdW material, and we hope it will become a versatile platform for investigating many others. Amazing team effort spearheaded by @luca_sor and great collaboration with the Hartschuh and Maier groups.

Paper out in Nature Photonics 🚀 We used layer by layer assembly to realize van der Waals heterostructure metasurfaces, which support strong light-matter interactions at room temperature and strong nonlinearities for next-generation photonic components.

Amazing work by shared first authors Lin, Andrea, and Thomas, and a great collaboration with Stefan in Monash and others. Will be a powerful platform for ultra confined nanophotonic systems, including strong coupling, IR sensing, and thermal management:

New paper out in @NaturePhotonics 📰🥳 We demonstrate phonon polariton bound states in the continuum metasurfaces in silicon carbide membranes. These qBICs are extremely subwavelength (10^5 smaller than free space) and show great robustness against incident-angle variations.
