In electronic systems, 2D WPs are inherently fragile due to spin\u2013orbit coupling, while photonic implementations typically rely on synthetic dimensions, resulting in only quasi-3D WPs. Here, we demonstrate genuine 2D WPs in an interlaced woven Kagome layer, where the out-of-plane braiding breaks inversion and mirror symmetries while preserving the layer-group symmetry LG 76 (p622) that pins chiral linear crossings at the Brillouin-zone vertices. By controlled stretching of one family of rods, we reduce the symmetry to a lower subgroup and directly track the motion of the WPs. The associated edge spectra reveal a controllable evolution from Weyl-connecting gapless states to a gapped valley-topological phase after full symmetry lifting. This work establishes a mechanically tunable platform for intrinsic 2D Weyl physics and reconfigurable topological wave transport.<\/jats:p>","DOI":"10.1364\/ol.599416","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T13:00:10Z","timestamp":1777035610000},"page":"2888","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Two-dimensional chiral Weyl points in an interlaced Kagome layer"],"prefix":"10.1364","volume":"51","author":[{"given":"Yundan","family":"Xia","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05htk5m33","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanlong","family":"Chen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05htk5m33","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zibo","family":"Liu","sequence":"additional","affiliation":[{"name":"Tsinghua University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6311-4510","authenticated-orcid":true,"given":"Qinghua","family":"Guo","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05htk5m33","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,5,11]]},"reference":[{"key":"ol-51-10-2888-R1","doi-asserted-by":"publisher","first-page":"13038","DOI":"10.1038\/ncomms13038","type":"journal-article","volume":"7","author":"Chen","year":"2016","journal-title":"Nat.
