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…
