Hyperbolic whispering-gallery mode nanocavity-confined phonon polaritons (PhPs) display a strongly enhanced light\u2013matter interaction in the infrared regime. Particularly, the unidirectional phonon-polarization excitation in nanocavities has a potential application value in an on-chip integrated optical circuit design, efficient optical sensors, and enhanced spectral technology. Here, we explore the hyperbolic whispering-gallery mode PhPs on the cross section of a hexagonal BN nanotube (BNNT) and demonstrate that efficient unidirectional excitation can be achieved using a circularly polarized electric dipole, combining with optical spin\u2013orbit coupling. Our results demonstrated that the undirectionality of the hyperbolic polariton propagation in a nanocavity can be conveniently achieved, independent of the structure symmetry of the nanocavity, providing potential applications in nanoscale light propagation, on-chip optical devices, and communication.<\/jats:p>","DOI":"10.1364\/ol.528798","type":"journal-article","created":{"date-parts":[[2024,7,2]],"date-time":"2024-07-02T16:04:02Z","timestamp":1719936242000},"page":"4082","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Unidirectional hyperbolic whispering-gallery phonon-polariton excitation in boron nitride nanotubes"],"prefix":"10.1364","volume":"49","author":[{"given":"Ranran","family":"Wang","sequence":"first","affiliation":[{"name":"University of Electronic Science and Technology of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5001-3390","authenticated-orcid":true,"given":"Zhihong","family":"Zhang","sequence":"additional","affiliation":[{"name":"University of Electronic Science and Technology of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2024,7,17]]},"reference":[{"key":"ol-49-15-4082-R1","doi-asserted-by":"publisher","first-page":"553","DOI":"10.1002\/lpor.201000025","volume":"5","author":"Ward","year":"2011","journal-title":"Laser Photonics Rev."},{"key":"ol-49-15-4082-R2","doi-asserted-by":"publisher","first-page":"185","DOI":"10.1007\/s11434-016-0996-z","volume":"61","author":"Xiao","year":"2016","journal-title":"Sci.
