Although such states hold great promise for suppressing optical crosstalk in integrated photonics, existing FBBS implementations suffer from significant radiation losses because of their eigenfrequencies lying within the bulk continuum. In this work, we introduce a double\u2010channel waveguide system based on honeycomb photonic lattices made of lithium niobate, which supports FBBSs with eigenfrequencies fully residing within the photonic band gap. This strategic positioning effectively suppresses radiation into bulk modes, enabling low\u2010loss photon propagation. Moreover, by leveraging the strong electro\u2010optic response of lithium niobate, we demonstrate dynamic and reversible tuning of the inter\u2010waveguide tunneling probability via an external voltage. Our platform not only overcomes the key limitations of prior FBBS designs but also offers a robust, tunable architecture for high\u2010performance on\u2010chip photonic devices such as lossless modulators, reconfigurable routers, and topological circuits.<\/jats:p>","DOI":"10.1002\/nap2.70232","type":"journal-article","created":{"date-parts":[[2026,8,5]],"date-time":"2026-08-05T12:40:08Z","timestamp":1785933608000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Radiation\u2010Free In\u2010Gap Finite Barrier Bound States in a Lithium Niobate\u2010Based Honeycomb Lattice"],"prefix":"10.1002","volume":"15","author":[{"given":"Yiru","family":"Du","sequence":"first","affiliation":[{"name":"National Key Laboratory of Microwave Photonics, College of Electronic and Information Engineering Nanjing University of Aeronautics and Astronautics  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9957-4533","authenticated-orcid":false,"given":"Zhixiong","family":"Xie","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Microwave Photonics, College of Electronic and Information Engineering Nanjing University of Aeronautics and Astronautics  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0488-8142","authenticated-orcid":false,"given":"Songyan","family":"Hou","sequence":"additional","affiliation":[{"name":"Photoner Co.
