These structures exhibit extraordinary six-month stability and resist erasure under the electric-field and thermal-cycling conditions investigated, indicating a persistent material modification rather than reversible reorientation. Polarization-dependent readout reveals nearly constant diffraction efficiency despite strongly anisotropic transmission of the host medium, indicating both phase and amplitude contributions to the optical response. Applied AC fields enable reversible, frequency-dependent modulation of diffracted intensity governed by slow dipolar dynamics. These findings establish NFLCs as a robust, non-volatile platform for electrically tuneable photonic devices, bridging the gap between fast dynamic holography and permanent optical memory.<\/jats:p>","DOI":"10.1364\/oe.604999","type":"journal-article","created":{"date-parts":[[2026,6,4]],"date-time":"2026-06-04T14:00:07Z","timestamp":1780581607000},"page":"27412","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Long-lived stationary holographic gratings and optical memory in ferroelectric nematic liquid crystals"],"prefix":"10.1364","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6799-1062","authenticated-orcid":true,"given":"Oleksandra","family":"Gridyakina","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00y0xnp53","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jakub","family":"Herman","sequence":"additional","affiliation":[{"name":"Military University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svitlana","family":"Bugaychuk","sequence":"additional","affiliation":[{"name":"PhLAM, University of Lille"},{"name":"Institute of Physics of NAS of Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janusz","family":"Parka","sequence":"additional","affiliation":[{"name":"Military University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,7,15]]},"reference":[{"key":"oe-34-15-27412-R1","doi-asserted-by":"publisher","first-page":"021001","DOI":"10.1103\/PhysRevE.106.021001","type":"journal-article","volume":"106","author":"Sebasti\u00e1n","year":"2022","journal-title":"Phys.
