This structure is fabricated by periodically splicing SMF and NCF segments, with the entire fiber skeleton subsequently etched to 30\u2009\u00b5m to trigger a full-interface evanescent leakage regime in PDMS for enhancing the temperature sensitivity. Experimental results show that the structure achieves the temperature sensitivity of \u22121.00\u2009nm\/\u00b0C within a compact sensing length of only 2.6\u2009mm. This work not only provides a high-performance tool for temperature sensing but also offers insights into the modal evolution of hybrid-waveguide-based photonic devices.\n                  <\/jats:p>","DOI":"10.1364\/ol.608771","type":"journal-article","created":{"date-parts":[[2026,6,24]],"date-time":"2026-06-24T17:00:09Z","timestamp":1782320409000},"page":"3973","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["High-sensitivity temperature sensor based on a compact etched assembled LPFG in a SiO\n                    <sub>2<\/sub>\n                    -PDMS hybrid waveguide"],"prefix":"10.1364","volume":"51","author":[{"given":"Yueyue","family":"Leng","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03x80pn82","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6323-4718","authenticated-orcid":true,"given":"Yiwei","family":"Ma","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03x80pn82","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Harbin Engineering University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Geng","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03x80pn82","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,7,10]]},"reference":[{"key":"ol-51-14-3973-R1","doi-asserted-by":"publisher","first-page":"e03863","DOI":"10.1002\/adom.202503863","type":"journal-article","volume":"14","author":"Zhang","year":"2026","journal-title":"Adv.
