Importantly, the unambiguous measurement has a prominent\n\t\t\t\t\tadvantage of detecting the arbitrary AM component rather than the\n\t\t\t\t\ttotal AM. The miniature metadevice offers the possibility of\n\t\t\t\t\tharnessing AM division on chip or in fiber and holds great promise to\n\t\t\t\t\tdelve the spin\u2013orbit interactions for topological photonics and\n\t\t\t\t\tquantum cryptography.<\/jats:p>","DOI":"10.1364\/ol.506824","type":"journal-article","created":{"date-parts":[[2023,12,4]],"date-time":"2023-12-04T10:00:09Z","timestamp":1701684009000},"page":"198","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Spin\u2013orbital angular momentum degeneracy breaking in nanoplasmonic metachain"],"prefix":"10.1364","volume":"49","author":[{"given":"Jia","family":"Chen","sequence":"first","affiliation":[{"name":"Xiamen University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiangtao","family":"Lv","sequence":"additional","affiliation":[{"name":"Northeastern University at Qinhuangdao"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongxin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Underwater Acoustic Communication and Marine Information Technology (Xiamen University)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangyuan","family":"Si","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengzhe","family":"Shen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05gsxrt27","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dapeng","family":"Wang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05gsxrt27","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Xiamen University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2024,1,1]]},"reference":[{"key":"ol-49-2-198-R1","doi-asserted-by":"publisher","first-page":"796","DOI":"10.1038\/nphoton.2015.201","volume":"9","author":"Bliokh","year":"2015","journal-title":"Nat.\n\t\t\t\t\tPhotonics"},{"key":"ol-49-2-198-R2","doi-asserted-by":"publisher","first-page":"59","DOI":"10.1038\/s41377-021-00474-0","volume":"10","author":"Zhang","year":"2021","journal-title":"Light: Sci.\n\t\t\t\t\tAppl."},{"key":"ol-49-2-198-R3","doi-asserted-by":"publisher","first-page":"343","DOI":"10.1038\/nphoton.2011.81","volume":"5","author":"Padgett","year":"2011","journal-title":"Nat.
