Here, we report a tunable\n\t\t\t\t\tmagneto-optical meta-waveguide that can achieve dual narrow-band\n\t\t\t\t\tnonreciprocal transmission of CPL via nonlocal chiral guided\n\t\t\t\t\tresonances (GRs). We show, by breaking time-reversal symmetry, that\n\t\t\t\t\tthe polarization states of two GRs at the \u0490 point can be simultaneously modulated\n\t\t\t\t\tfrom linear to circular polarization by applying external magnetic\n\t\t\t\t\tfields, enabling dual-band unidirectional transmission of CPL with a\n\t\t\t\t\tcontrast ratio up to 48\u2009dB. Calculation results further reveal that\n\t\t\t\t\thigh-quality (Q) chiral GRs are governed by spin-selective electric\n\t\t\t\t\tquadrupole and magnetic dipole resonances with a Q factor of 10\n                    <jats:sup>5<\/jats:sup>\n                    . Moreover, the wavelength of\n\t\t\t\t\tasymmetric transmission can be tuned by modifying structural\n\t\t\t\t\tparameters, while giant transmission contrast remains higher than\n\t\t\t\t\t35\u2009dB. Our design offers versatility for advanced chiral wave\n\t\t\t\t\tmanipulation, promising applications in optical communication,\n\t\t\t\t\tultra-narrow spin filters, and nonreciprocal devices.\n                  <\/jats:p>","DOI":"10.1364\/ol.613644","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T13:42:02Z","timestamp":1791466922000},"page":"5846","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Active spin-selection and nonreciprocal transmission via nonlocal chiral guided resonance in magneto-optical meta-waveguides"],"prefix":"10.1364","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5285-9392","authenticated-orcid":true,"given":"Wu","family":"Fei","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02czkny70","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Hefei University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengchen","family":"Bi","sequence":"additional","affiliation":[{"name":"Hefei University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiheng","family":"Zhang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02czkny70","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuying","family":"Yang","sequence":"additional","affiliation":[{"name":"Hefei University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youlong","family":"Yu","sequence":"additional","affiliation":[{"name":"Hefei University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7973-1065","authenticated-orcid":true,"given":"Jigang","family":"Hu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02czkny70","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,10,13]]},"reference":[{"key":"ol-51-20-5846-R1","doi-asserted-by":"publisher","first-page":"659","DOI":"10.1038\/s42254-023-00642-8","type":"journal-article","volume":"5","author":"Kang","year":"2023","journal-title":"Nat.
