The layered \u03b1-MoO\n                    <jats:sub>3<\/jats:sub>\n                    shows transparent in-plane birefringence in the visible wavelength range due to its large bandgap above 3.0\u2009eV, which enables the precise tuning of the ERs and optical reflectivity by simply tailoring the resonance conditions of the optical cavities to achieve narrowband polarization selectivity with both markedly high extinction ratios (ERs) and optical reflectivity. Using layered \u03b1-MoO\n                    <jats:sub>3<\/jats:sub>\n                    on a Si\/SiO\n                    <jats:sub>2<\/jats:sub>\n                    substrate as an example, systematic analysis based on the scattering matrix method shows that a high-performance polarizer with an ER\u2009&gt;\u200910\u2009dB and an optical reflectivity\u2009&gt;\u20090.5 can be obtained in the wavelength range of 400\u2013490\u2009nm. The central polarization wavelength can be tuned by varying the thickness of the \u03b1-MoO\n                    <jats:sub>3<\/jats:sub>\n                    layer. Experimental results validate the proposed design strategy, demonstrating the feasibility of constructing high-performance, miniaturized polarizers using transparent anisotropic van der Waals crystals. This approach shows strong potential for applications in on-chip photonic integration, polarization optics, and next-generation optical communication systems.\n                  <\/jats:p>","DOI":"10.1364\/ol.591674","type":"journal-article","created":{"date-parts":[[2026,2,25]],"date-time":"2026-02-25T19:00:10Z","timestamp":1772046010000},"page":"1653","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["High-performance nanoscale polarizers enabled by transparent birefringence of layered \u03b1-MoO\n                    <sub>3<\/sub>"],"prefix":"10.1364","volume":"51","author":[{"given":"Jingwen","family":"Song","sequence":"first","affiliation":[{"name":"Tianjin University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baoxin","family":"Niu","sequence":"additional","affiliation":[{"name":"Tianjin University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruitong","family":"Wang","sequence":"additional","affiliation":[{"name":"Tianjin University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiale","family":"Wang","sequence":"additional","affiliation":[{"name":"Tianjin University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yeqin","family":"Li","sequence":"additional","affiliation":[{"name":"Tianjin University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Liu","sequence":"additional","affiliation":[{"name":"Tianjin University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6485-904X","authenticated-orcid":true,"given":"Chunguang","family":"Hu","sequence":"additional","affiliation":[{"name":"Tianjin University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3932-5457","authenticated-orcid":true,"given":"Wanfu","family":"Shen","sequence":"additional","affiliation":[{"name":"Tianjin University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,3,12]]},"reference":[{"key":"ol-51-6-1653-R1","doi-asserted-by":"publisher","first-page":"5464258","DOI":"10.34133\/2020\/5464258","type":"journal-article","volume":"2020","author":"Li","year":"2020","journal-title":"Research"},{"key":"ol-51-6-1653-R2","author":"Hecht","year":"2002"},{"key":"ol-51-6-1653-R3","author":"Macleod","year":"2010"},{"key":"ol-51-6-1653-R4","doi-asserted-by":"publisher","first-page":"937","DOI":"10.1038\/nnano.2015.186","type":"journal-article","volume":"10","author":"Arbabi","year":"2015","journal-title":"Nat.
