Conventional ONNs focus on handling limited information dimensions such as optical amplitude and phase, which are confined to simple small\u2010size image classification, raising demand for significant reconfigurability on the perception of inherent high\u2010dimensional light information. Herein, magneto\u2010optoelectronic devices with polarization sensitivity are theoretically proposed to construct the ONN with high\u2010performance multidimensional recognition, which is composed of 2D magnetic half\u2010metal FeCl\n                    <jats:sub>2<\/jats:sub>\n                    and 2H\u2010WSe\n                    <jats:sub>2<\/jats:sub>\n                    . Polarization sensitivity with photogalvanic effect originates from the space\u2010inversion symmetrical breaking of 2H\u2010WSe\n                    <jats:sub>2<\/jats:sub>\n                    , yielding the multidimensional perception under zero power consumption. The switchable magnetic configuration of two FeCl\n                    <jats:sub>2<\/jats:sub>\n                    contacts with unique half\u2010metal band structures nonvolatilely modulates the amplitude and polarity of photoresponse across the wavelength from ultraviolet to near\u2010infrared. By leveraging multidimensional light encoding, the proposed ONN architecture conducts negative value and nonlinear computations in polarization domain through highly reconfigurable magneto\u2010optoelectronic mechanisms, which achieves up to 93.5% accuracy across complex tasks including 3D object classification, time\u2010series recognition, etc. This work illuminates the potential of magneto\u2010electronics, which extends the applications of ONNs in the real world.\n                  <\/jats:p>","DOI":"10.1002\/smsc.202500487","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T06:15:50Z","timestamp":1765174550000},"source":"Crossref","is-referenced-by-count":1,"title":["Reconfigurable Magneto\u2010Optoelectronic Devices for Multidimensional Optical Neural Network"],"prefix":"10.1002","volume":"6","author":[{"given":"Haiyan","family":"He","sequence":"first","affiliation":[{"name":"Beijing National Research Center for Information Science and Technology School of Integrated Circuits Tsinghua University  Beijing 100084 China"},{"name":"School of Physics Beihang University  Beijing 100191 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Cheng","sequence":"additional","affiliation":[{"name":"School of Artificial Intelligence Shanghai Jiao Tong University  Shanghai 200030 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5088-2865","authenticated-orcid":false,"given":"Wenxuan","family":"Zhu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Materials (MOE) School of Materials Science and Engineering Tsinghua University  Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiacheng","family":"Sun","sequence":"additional","affiliation":[{"name":"Beijing National Research Center for Information Science and Technology School of Integrated Circuits Tsinghua University  Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaming","family":"Sun","sequence":"additional","affiliation":[{"name":"Beijing National Research Center for Information Science and Technology School of Integrated Circuits Tsinghua University  Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tonglu","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing National Research Center for Information Science and Technology School of Integrated Circuits Tsinghua University  Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng","family":"Song","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Materials (MOE) School of Materials Science and Engineering Tsinghua University  Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Pan","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Materials (MOE) School of Materials Science and Engineering Tsinghua University  Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4860-8774","authenticated-orcid":false,"given":"Junying","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Physics Beihang University  Beijing 100191 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6369-7103","authenticated-orcid":false,"given":"Yuyan","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing National Research Center for Information Science and Technology School of Integrated Circuits Tsinghua University  Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,7]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nphoton.2017.93"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41566-020-00754-y"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s42254-023-00645-5"},{"key":"e_1_2_9_5_1","doi-asserted-by":"crossref","unstructured":"Z.Liu Y.Lin Y.Cao H.Hu Y.Wei Z.Zhang S.Lin B.Guo inProc.
