Here, the topological stability of photonic spin meron lattices, which indicates the invariance of skyrmion number and robustness of spin texture under a continuous deformation of the field configuration, is demonstrated by inducing a perturbation to break the\n                    <jats:italic>C<\/jats:italic>\n                    <jats:sub>4<\/jats:sub>\n                    symmetry in the presence spin-orbit coupling in an optical field. We revealed that amplitude perturbation would result in an amplitude-dependent shift of spin center, while phase perturbation leads to the deformation of domain walls, manifesting the metastability of photonic meron. Such spin topology is verified through the interference of plasmonic vortices with a broken rotational symmetry. The results provide new insights on optical topological quasiparticles, which may pave the way towards applications in topological photonics, optical information storage and transfer.\n                  <\/jats:p>","DOI":"10.1364\/oe.479282","type":"journal-article","created":{"date-parts":[[2023,1,3]],"date-time":"2023-01-03T10:00:28Z","timestamp":1672740028000},"page":"2225","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Metastability of photonic spin meron lattices in the presence of perturbed spin-orbit coupling"],"prefix":"10.1364","volume":"31","author":[{"given":"Xinrui","family":"Lei","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00ay9v204","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Zhangjiang Laboratory"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luping","family":"Du","sequence":"additional","affiliation":[{"name":"Shenzhen University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaocong","family":"Yuan","sequence":"additional","affiliation":[{"name":"Shenzhen University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8745-4213","authenticated-orcid":true,"given":"Qiwen","family":"Zhan","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00ay9v204","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Zhangjiang Laboratory"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2023,1,9]]},"reference":[{"key":"oe-31-2-2225-R1","doi-asserted-by":"publisher","first-page":"797","DOI":"10.1038\/nature05056","volume":"442","author":"Rossler","year":"2006","journal-title":"Nature"},{"key":"oe-31-2-2225-R2","doi-asserted-by":"publisher","first-page":"901","DOI":"10.1038\/nature09124","volume":"465","author":"Yu","year":"2010","journal-title":"Nature"},{"key":"oe-31-2-2225-R3","doi-asserted-by":"publisher","first-page":"915","DOI":"10.1126\/science.1166767","volume":"323","author":"M\u00fchlbauer","year":"2009","journal-title":"Science"},{"key":"oe-31-2-2225-R4","doi-asserted-by":"publisher","first-page":"031045","DOI":"10.1103\/PhysRevX.4.031045","volume":"4","author":"Banerjee","year":"2014","journal-title":"Phys.
