By breaking certain spatial symmetries, chiral structures arise and provide robust chiroptical responses to these plasmonic resonances. Here, we observe strong chiroptical responses in the linear and nonlinear optical regime for chiral L-handed helicoid-III nanoparticles and quantify them by means of an asymmetric factor, the so-called g-factor. We calculate the linear optical g-factors for two distinct chiroptical resonances to −0.12 and –0.43 and the nonlinear optical g-factors to −1.45 and −1.63. The results demonstrate that the chirality of the helicoid-III nanoparticles is strongly enhanced in the nonlinear regime."}],"volume":9,"oa":"1","keyword":["Electrical and Electronic Engineering","Atomic and Molecular Physics","and Optics","Biotechnology","Electronic","Optical and Magnetic Materials"],"issue":"3","publication":"ACS Photonics","date_created":"2022-03-03T07:18:18Z","type":"journal_article","page":"784–792","publication_identifier":{"issn":["2330-4022","2330-4022"]},"_id":"30195","intvolume":"         9","year":"2022","status":"public","author":[{"last_name":"Spreyer","full_name":"Spreyer, Florian","first_name":"Florian"},{"full_name":"Mun, Jungho","last_name":"Mun","first_name":"Jungho"},{"first_name":"Hyeohn","last_name":"Kim","full_name":"Kim, Hyeohn"},{"full_name":"Kim, Ryeong Myeong","last_name":"Kim","first_name":"Ryeong Myeong"},{"last_name":"Nam","full_name":"Nam, Ki Tae","first_name":"Ki Tae"},{"first_name":"Junsuk","last_name":"Rho","full_name":"Rho, Junsuk"},{"last_name":"Zentgraf","full_name":"Zentgraf, Thomas","id":"30525","orcid":"0000-0002-8662-1101","first_name":"Thomas"}],"main_file_link":[{"url":"https://pubs.acs.org/doi/full/10.1021/acsphotonics.1c00882","open_access":"1"}],"article_type":"original","citation":{"apa":"Spreyer, F., Mun, J., Kim, H., Kim, R.
