We also present experimental validation for an axisymmetric inverse-designed monochrome lens in the near-infrared fabricated via two-photon polymerization. Axisymmetry allows fullwave Maxwell solvers to be scaled up to structures hundreds or even thousands of wavelengths in diameter before requiring domain-decomposition approximations, while multilayer topology optimization with ∼105 degrees of freedom can tackle challenging design problems even when restricted to axisymmetric structures.","lang":"eng"}],"article_processing_charge":"No","day":"26","intvolume":"        28","external_id":{"arxiv":["2007.11661"],"pmid":["33182865"]},"publication":"Optics Express","OA_type":"gold","date_published":"2020-10-26T00:00:00Z","DOAJ_listed":"1","volume":28,"language":[{"iso":"eng"}],"ddc":["530"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Optica Publishing Group","doi":"10.1364/oe.403192","year":"2020","title":"Fullwave Maxwell inverse design of axisymmetric, tunable, and multi-scale multi-wavelength metalenses","page":"33854-33868","extern":"1","_id":"21637","issue":"23","article_type":"original","publication_status":"published","quality_controlled":"1","author":[{"first_name":"Rasmus E.","full_name":"Christiansen, Rasmus E.","last_name":"Christiansen"},{"full_name":"Lin, Zin","first_name":"Zin","last_name":"Lin"},{"first_name":"Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","full_name":"Roques-Carmes, Charles","last_name":"Roques-Carmes"},{"last_name":"Salamin","first_name":"Yannick","full_name":"Salamin, Yannick"},{"first_name":"Steven E.","full_name":"Kooi, Steven E.","last_name":"Kooi"},{"full_name":"Joannopoulos, John D.","first_name":"John D.","last_name":"Joannopoulos"},{"last_name":"Soljačić","full_name":"Soljačić, Marin","first_name":"Marin"},{"full_name":"Johnson, Steven G.","first_name":"Steven G.","last_name":"Johnson"}],"OA_place":"publisher","status":"public","main_file_link":[{"url":"https://doi.org/10.1364/OE.403192","open_access":"1"}],"month":"10"}
