Collective near-field coupling in infrared-phononic metasurfaces for nano-light canalization
Peining Li, Guangwei Hu, Irene Dolado +10
Polaritons, coupled excitations of photons and dipolar matter excitations, can propagate along anisotropic metasurfaces with either hyperbolic or elliptical dispersion. At the tran…

Nonlinear Metasurfaces: A Paradigm Shift in Nonlinear Optics
Alexander Krasnok, Mykhailo Tymchenko, Andrea Alu
Frequency conversion processes, such as second- and third-harmonic generation, are one of the most common effects in nonlinear optics which offer many opportunities for photonics,…
