In particular, polaritons with a flatband dispersion allow for mode canalization and diffractionless propagation, which showcase advantages for on-chip technologies requiring long-range transportation of optical information. Here, we propose a flatband polaritonic router based on twisted \u03b1-MoO\n                    <jats:sub>3<\/jats:sub>\n                    bilayers, which allows for on-chip routing of highly confined and low-loss phonon polaritons (PhPs) along multichannel propagating paths under different circular polarized dipole excitations. Our work combines flatband physics and optical spin\u2013 orbit coupling, with potential applications in nanoscale light propagation, on-chip optical switching, and communication.\n                  <\/jats:p>","DOI":"10.1364\/ol.496630","type":"journal-article","created":{"date-parts":[[2023,7,6]],"date-time":"2023-07-06T10:00:34Z","timestamp":1688637634000},"page":"4073","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Flatband polaritonic router in twisted bilayer van der Waals materials"],"prefix":"10.1364","volume":"48","author":[{"given":"Haoran","family":"Lv","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04qr3zq92","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6383-1248","authenticated-orcid":true,"given":"Yihua","family":"Bai","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04qr3zq92","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qing","family":"Zhang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04qr3zq92","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5901-2872","authenticated-orcid":true,"given":"Yuanjie","family":"Yang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04qr3zq92","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2023,7,25]]},"reference":[{"key":"ol-48-15-4073-R1","doi-asserted-by":"publisher","first-page":"187","DOI":"10.1038\/s41586-021-03581-5","volume":"597","author":"Zhang","year":"2021","journal-title":"Nature"},{"key":"ol-48-15-4073-R2","doi-asserted-by":"publisher","first-page":"184","DOI":"10.1126\/science.abn6528","volume":"376","author":"Said Ergoktas","year":"2022","journal-title":"Science"},{"key":"ol-48-15-4073-R3","doi-asserted-by":"publisher","first-page":"682","DOI":"10.1038\/nnano.2015.131","volume":"10","author":"Dai","year":"2015","journal-title":"Nat.
