Polaritonic metasurfaces

Aula Seminari (Pal. RM004)

Professor Andrea Alù

Distinguished Professor at the City University of New York (CUNY), the Founding Director of the Photonics Initiative, CUNY Advanced
Science Research Center, and the Einstein Professor of Physics at the CUNY Graduate Center.


In this talk, I discuss our recent efforts in the context of nano-optics and photonics, with a special emphasis on strong light-matter interactions enabled by exciton, phonon and electronic resonances in polaritonic metasurfaces. I will discuss our recent theoretical and experimental results in the context of polariton manipulation based on excitons, intersubband transitions and phonons interacting with light.
The combination of these features with photonic engineering enables giant optical nonlinearities, efficient nanoscale light manipulation and topological transitions. During the talk, I will discuss the exotic light-matter interactions arising in these systems, and their opportunities for wave physics and photonics technologies.
