The orbit\u2013orbit interaction is originating from the coupling between different vortices and antivortices. Based on this process, we reveal the resultant controllable orbital\u2013angular\u2013momentum Hall effect by considering a typical structure, which comprises a vortex\u2013antivortex pair and another vortex (or antivortex) as a controllable knob. The intrinsic Hall effect can be spatially manipulated by appropriately engineering the orbit\u2013orbit interaction, namely arranging the initial distribution of these elements. This work can find interesting potential applications. For example, it provides an effective technique for controllable paired photon generation.<\/jats:p>","DOI":"10.1364\/ol.511460","type":"journal-article","created":{"date-parts":[[2024,1,2]],"date-time":"2024-01-02T10:00:20Z","timestamp":1704189620000},"page":"646","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Controllable orbital\u2013angular\u2013momentum Hall effect by engineering intrinsic orbit\u2013orbit interaction"],"prefix":"10.1364","volume":"49","author":[{"given":"Jianbin","family":"Ren","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02xe5ns62","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Guangdong Provincial Key Laboratory of Optical Fiber Sensing and Communications"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haolin","family":"Lin","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02xe5ns62","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Guangdong Provincial Key Laboratory of Optical Fiber Sensing and Communications"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yixuan","family":"Liao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02xe5ns62","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Guangdong Provincial Key Laboratory of Optical Fiber Sensing and Communications"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Yin","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02xe5ns62","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Guangdong Provincial Key Laboratory of Optical Fiber Sensing and Communications"},{"name":"Guangdong Provincial Engineering Research Center of Crystal and Laser Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02xe5ns62","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Guangdong Provincial Key Laboratory of Optical Fiber Sensing and Communications"},{"name":"Guangdong Provincial Engineering Research Center of Crystal and Laser Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenqiang","family":"Chen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02xe5ns62","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Guangdong Provincial Key Laboratory of Optical Fiber Sensing and Communications"},{"name":"Guangdong Provincial Engineering Research Center of Crystal and Laser Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8417-4929","authenticated-orcid":true,"given":"Shenhe","family":"Fu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02xe5ns62","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Guangdong Provincial Key Laboratory of Optical Fiber Sensing and Communications"},{"name":"Guangdong Provincial Engineering Research Center of Crystal and Laser Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2024,1,26]]},"reference":[{"key":"ol-49-3-646-R1","doi-asserted-by":"publisher","first-page":"299","DOI":"10.1002\/lpor.200810007","volume":"2","author":"Franke-Arnold","year":"2008","journal-title":"Laser Photonics Rev."},{"key":"ol-49-3-646-R2","doi-asserted-by":"publisher","first-page":"064004","DOI":"10.1088\/2040-8978\/18\/6\/064004","volume":"18","author":"Barnett","year":"2016","journal-title":"J.
