Polarization control via artificial optical nonlinearity in dielectric metasurfaces
Fuyong Yue, Giacomo Balistreri, Nicola Montaut +6
Nonlinear optical phenomena are generally governed by geometry in matter systems, as they depend on the spatial arrangement of atoms within materials or molecules. Metasurfaces, th…
