In this work, we introduce a novel approach to manipulate the orientation of photonic OAM at subwavelength scales, leveraging spatiotemporal coupling. By tightly focusing a wavepacket containing dual spatiotemporal vortices and a spatial vortex through a high numerical aperture lens, the emergence of intricate coupling phenomena leads to entangled and intricately twisted vortex tunnels. As a consequence, the orientation of spatial OAM deviates from the conventional light axis. Through theoretical scrutiny, we unveil that the orientation of photonic OAM within the focal field is contingent upon the signs of the topological charges in both spatiotemporal and spatial domains. Additionally, the absolute values of these charges govern the precise orientation of OAM within their respective quadrants. Moreover, augmenting the pulse width of the incident light engenders a more pronounced deflection angle of photonic OAM. By astutely manipulating these physical parameters, unparalleled control over the spatial orientation of OAM becomes achievable. The augmented optical degrees of freedom introduced by this study hold considerable potential across diverse domains, including optical tweezers, spin-orbit angular momentum coupling, and quantum communication.<\/jats:p>","DOI":"10.1364\/oe.509594","type":"journal-article","created":{"date-parts":[[2023,12,12]],"date-time":"2023-12-12T03:01:49Z","timestamp":1702350109000},"page":"526","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Spatiotemporal coupling induced controllable orientation of photonic orbital angular momentum at subwavelength scale"],"prefix":"10.1364","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-8157-5685","authenticated-orcid":true,"given":"Zhaorui","family":"Zhang","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ct4d772","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Si","family":"Gu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ct4d772","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7060-6046","authenticated-orcid":true,"given":"Bing","family":"Gu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ct4d772","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Shandong Normal University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bingjue","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ct4d772","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3527-6309","authenticated-orcid":true,"given":"Guanghao","family":"Rui","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ct4d772","id-type":"ROR","asserted-by":"publisher"}]},{"name":"University of Shanghai for Science and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2023,12,19]]},"reference":[{"key":"oe-32-1-526-R1","doi-asserted-by":"publisher","first-page":"335","DOI":"10.1038\/nphoton.2011.80","volume":"5","author":"Dholakia","year":"2011","journal-title":"Nat.
