Abstract

Metasurfaces supporting bound states in the continuum (BICs) have emerged as a powerful nanophotonic platform because of their exceptional resonance control and large field enhancements ideal for light-matter coupling. Van der Waals (vdW) materials are particularly interesting for nanophotonics because of their unique optical and electronic properties. This talk will introduce BIC-driven metasurface concepts based on the prominent vdW materials hexagonal boron nitride and the transition metal dichalcogenide WS2, demonstrating broad spectral tunability, ultrasharp resonances, and strong light-matter coupling. Material-intrinsic BIC platforms are broadly applicable for many vdW materials and especially TMDs, delivering both basic insights and practical polaritonic devices.
