Efficient and tunable narrowband second-harmonic generation by a large-area etchless lithium niobate metasurface
Yaping Hou, Yigong Luan, Yu Fan +8
Optical resonances in nanostructures enable strong enhancement of nonlinear processes at the nanoscale, such as second-harmonic generation (SHG), with high- modes providing inte…

All-optical polarization control and routing by nonlinear interferometry at the nanoscale
Yigong Luan, Attilio Zilli, Agostino Di Francescantonio +7
Optical metasurfaces are rapidly establishing as key-enabling platforms for nanophotonics applications. Along with the ability of taming light in subwavelength thicknesses, they ca…
