Giant Second Harmonic Generation from Membrane Metasurfaces.
Qu L, Bai L, Jin C, Liu Q, Wu W, Gao B, Li J, Cai W, Ren M, Xu J. Qu L, et al. Nano Lett. 2022 Dec 14;22(23):9652-9657. doi: 10.1021/acs.nanolett.2c03811. Epub 2022 Nov 29. Nano Lett. 2022. PMID: 36445198
Metasurfaces have emerged as a fascinating framework for nonlinear optics, which have advantages of a compact footprint and unprecedented flexibility in manipulating light. But their nonlinear responses are generally limited by the short interaction lengths with light. The …
