Novel 2D van der Waals semiconductors facilitate the formation of heterostructures and thus support bandgap engineering for atomically thin modern photonic applications. When these heterostructures form a type II band structure, interlayer excitons (

Active metasurfaces hold great promise for spatial light modulation, and electro-optic tuning using lithium niobate is particularly attractive due to its high transparency and well-established thin-film platform. In this work, we present a free-space

Atomic beams offer measurement capabilities for hot vapors but often require complex, bulky systems, limiting miniaturization. This study explores hot vapors in thin cells (L=30,5 microns) as a simplified analogy to atomic beams. Coherence is maintai
