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…

Ray dynamics of whispering-gallery modes in curved space
Yongsheng Wang, Xiaoxuan Luo, Zaoyu Chen +6
Microcavities supporting Whispering-gallery modes (WGMs) are of great significance for on-chip optical information processing, which is frequently analyzed using ray dynamics that…
