Metasurfaces and Nanoantennas for Nonlinear and Quantum Applications
Metasurfaces and nanoantennas are a powerful class of nanostructured materials enabling unprecedented control of light–matter interaction. By overcoming limitations of traditional optics, they have become key platforms for advancing nonlinear and quantum photonics. These structures support applications ranging from secure communications and sensing to imaging and quantum information processing. Recent breakthroughs include high-harmonic generation, ultrafast all-optical switching, and quantum light generation enhanced by resonances.
