The most prominent example, the Pancharatnam\u2013Berry (PB) phase, originates from polarization evolution during wave propagation. In contrast, geometric phases associated with optical resonances and cavities remain largely unexplored. Here, we uncover the relation between the generalized PB phase and the far-field polarization evolution in bound states in the continuum (BIC) cavities. We demonstrate the continuous homotopic evolution of vortex lasing modes through geometric-phase engineering of BIC resonances. To experimentally validate this concept, we realize metasurface lasers composed of titanium dioxide hole arrays integrated with CdSe\/CdxZn1\u2013xS core\/shell colloidal quantum wells as the gain medium. Our results reveal a previously unexplored form of spin\u2013orbit interaction in BIC cavities under oblique incidence and provide a versatile route for on-chip control of polarization and orbital angular momentum in nanolasers.<\/jats:p>","DOI":"10.1021\/acs.nanolett.6c02899","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T14:01:59Z","timestamp":1790690519000},"page":"13802-13809","source":"Crossref","is-referenced-by-count":0,"title":["Homotopic Vortex\nLasing Mediated by a Resonant Geometric\nPhase in a Bound States in the Continuum Cavity"],"prefix":"10.1021","volume":"26","author":[{"given":"Ronghui","family":"Lin","sequence":"first","affiliation":[{"name":"Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR) , 2 Fusionopolis Way, Innovis #08-03 , ,","place":["Singapore, Republic of Singapore, 138634"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thi Thu Ha","family":"Do","sequence":"additional","affiliation":[{"name":"Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR) , 2 Fusionopolis Way, Innovis #08-03 , ,","place":["Singapore, Republic of Singapore, 138634"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6840-8342","authenticated-orcid":true,"given":"Emek Goksu","family":"Durmusoglu","sequence":"additional","affiliation":[{"name":"Nanyang Technological University , , ,","place":["Singapore, Singapore, 639798"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5733-3952","authenticated-orcid":true,"given":"Deepak K.","family":"Sharma","sequence":"additional","affiliation":[{"name":"Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR) , 2 Fusionopolis Way, Innovis #08-03 , ,","place":["Singapore, Republic of Singapore, 138634"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed","family":"Akhil","sequence":"additional","affiliation":[{"name":"Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR) , 2 Fusionopolis Way, Innovis #08-03 , ,","place":["Singapore, Republic of Singapore, 138634"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vytautas","family":"Valuckas","sequence":"additional","affiliation":[{"name":"Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR) , 2 Fusionopolis Way, Innovis #08-03 , ,","place":["Singapore, Republic of Singapore, 138634"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corentin","family":"Dabard","sequence":"additional","affiliation":[{"name":"Nanyang Technological University , , ,","place":["Singapore, Singapore, 639798"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arseniy I.","family":"Kuznetsov","sequence":"additional","affiliation":[{"name":"Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR) , 2 Fusionopolis Way, Innovis #08-03 , ,","place":["Singapore, Republic of Singapore, 138634"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1793-112X","authenticated-orcid":true,"given":"Hilmi Volkan","family":"Demir","sequence":"additional","affiliation":[{"name":"Nanyang Technological University , , ,","place":["Singapore, Singapore, 639798"]},{"name":"Bilkent University , , ,","place":["Ankara, Turkey, 06800"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5331-3092","authenticated-orcid":true,"given":"Jinghua","family":"Teng","sequence":"additional","affiliation":[{"name":"Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR) , 2 Fusionopolis Way, Innovis #08-03 , ,","place":["Singapore, Republic of Singapore, 138634"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5475-8365","authenticated-orcid":true,"given":"Son Tung","family":"Ha","sequence":"additional","affiliation":[{"name":"Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR) , 2 Fusionopolis Way, Innovis #08-03 , ,","place":["Singapore, Republic of Singapore, 138634"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,29]]},"reference":[{"key":"2026101408322314600_cit1","doi-asserted-by":"publisher","first-page":"1627","DOI":"10.1038\/s41565-024-01763-6","article-title":"Local control\nof polarization and geometric phase in thermal metasurfaces","volume":"19","author":"Nolen","year":"2024","journal-title":"Nat.
