We show that this enhancement originates from a new type of multi-mode Fano mechanism. These ‘Super-Fano’ resonances are investigated numerically in great detail using full-wave simulations. The theoretically predicted behavior of the metasurface is experimentally verified by linear and nonlinear transmission spectroscopy. Moreover, quantitative nonlinear measurements are performed, in which an absolute conversion efficiency as high as ηmax ≈ 2.8 × 10−7 a peak power intensity of 1.2 GW cm−2 is found. Compared to an unpatterned silicon film of the same thickness amplification factors of up to ~900 are demonstrated. Our results pave the way to exploiting a strong Fano-type multi-mode coupling in metasurfaces for high THG in potential applications.","lang":"eng"}],"doi":"https://doi.org/10.1038/s41377-023-01134-1","author":[{"full_name":"Hähnel, David","first_name":"David","last_name":"Hähnel"},{"last_name":"Golla","full_name":"Golla, Christian","first_name":"Christian"},{"last_name":"Albert","first_name":"Maximilian","full_name":"Albert, Maximilian"},{"full_name":"Zentgraf, Thomas","first_name":"Thomas","id":"30525","last_name":"Zentgraf","orcid":"0000-0002-8662-1101"},{"full_name":"Myroshnychenko, Viktor","first_name":"Viktor","id":"46371","last_name":"Myroshnychenko"},{"first_name":"Jens","full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","id":"158","last_name":"Förstner"},{"orcid":"https://orcid.org/0000-0002-3787-3572","id":"20798","last_name":"Meier","first_name":"Cedrik","full_name":"Meier, Cedrik"}],"date_created":"2023-04-21T09:45:07Z","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"has_accepted_license":"1"}
