To fully utilize such rich degrees of freedom of light, it is highly anticipated to separate the coupled angular momentum with a simple but powerful method, and the optical Hall effect becomes a promising scheme. Recently, the spin-orbit optical Hall effect has been proposed in terms of general vector vortex light using two anisotropic crystals. However, angular momentum separation for \u03c0-vector vortex modes, another important part in vector optical fields, have not been explored and it remains challenging to realize broadband response. Here, the wavelength-independent spin-orbit optical Hall effect in \u03c0-vector fields has been analyzed based on Jones matrices and verified experimentally using a single-layer liquid-crystalline film with designed holographic structures. Every \u03c0-vector vortex mode can be decoupled into spin and orbital components with equal magnitude but opposite signs. Our work could enrich the fields of high-dimensional optics.<\/jats:p>","DOI":"10.1364\/oe.493116","type":"journal-article","created":{"date-parts":[[2023,5,19]],"date-time":"2023-05-19T09:00:11Z","timestamp":1684486811000},"page":"19657","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Spin-orbit optical Hall effect in \u03c0-vector fields"],"prefix":"10.1364","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8800-6025","authenticated-orcid":true,"given":"Ziyao","family":"Lyu","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0220qvk04","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4144-3268","authenticated-orcid":true,"given":"Changshun","family":"Wang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0220qvk04","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2023,5,26]]},"reference":[{"key":"oe-31-12-19657-R1","doi-asserted-by":"publisher","first-page":"30473","DOI":"10.1364\/OE.433972","volume":"29","author":"Zhang","year":"2021","journal-title":"Opt.
