Conventional designs rely on bulky optical components, which restrict both device miniaturization and integration density. Computational spectral reconstruction has recently emerged as a promising strategy by eliminating optical dispersive elements and exploiting the intrinsic resolution of detector responses. Here, we report a miniaturized single\u2010detector computational spectrometer based on a mixed\u2010dimensional InSe\/GaN heterojunction, which achieves spectral sensing and reconstruction across the 300\u2013960\u00a0nm wavelength range within a compact footprint of 30 \u00d7 30 \u00b5m\n                    <jats:sup>2<\/jats:sup>\n                    . Additionally, it enables quantitative estimation of incident light power density in representative UV, visible, and NIR regions. We further validate its utility in imaging and bioinspired tetrachromatic vision tasks, highlighting its ability to perceive and reconstruct spectral information beyond the visible range. These results establish an effective pathway toward compact broadband computational spectrometers.\n                  <\/jats:p>","DOI":"10.1002\/smll.75182","type":"journal-article","created":{"date-parts":[[2026,8,11]],"date-time":"2026-08-11T09:25:56Z","timestamp":1786440356000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["UV\u2010Visible\u2010NIR Miniaturized Spectrometer Based on InSe\/GaN Heterojunction"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5789-0583","authenticated-orcid":false,"given":"Yujing","family":"Wang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Semiconductor Physics and Chip Technologies Institute of Semiconductors Chinese Academy of Sciences  Beijing China"},{"name":"Center of Materials Science and Optoelectronics Engineering University of Chinese Academy of Sciences  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Wang","sequence":"additional","affiliation":[{"name":"Tianjin Key Laboratory of Intelligent Control of Electrical Equipment TianGong University  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Hu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Semiconductor Physics and Chip Technologies Institute of Semiconductors Chinese Academy of Sciences  Beijing China"},{"name":"Center of Materials Science and Optoelectronics Engineering University of Chinese Academy of Sciences  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiawei","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Semiconductor Physics and Chip Technologies Institute of Semiconductors Chinese Academy of Sciences  Beijing China"},{"name":"Tianjin Key Laboratory of Intelligent Control of Electrical Equipment TianGong University  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-1574-7379","authenticated-orcid":false,"given":"Hui","family":"Wen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Semiconductor Physics and Chip Technologies Institute of Semiconductors Chinese Academy of Sciences  Beijing China"},{"name":"Center of Materials Science and Optoelectronics Engineering University of Chinese Academy of Sciences  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4583-6365","authenticated-orcid":false,"given":"Yuqing","family":"Huang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Semiconductor Physics and Chip Technologies Institute of Semiconductors Chinese Academy of Sciences  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2746-2363","authenticated-orcid":false,"given":"Zhongchao","family":"Fan","sequence":"additional","affiliation":[{"name":"Engineering Research Center For Semiconductor Integrated Technology Institute of Semiconductors Chinese Academy of Sciences  Beijing China"},{"name":"School of Integrated Circuits University of Chinese Academy of Sciences  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lixia","family":"Zhao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Semiconductor Physics and Chip Technologies Institute of Semiconductors Chinese Academy of Sciences  Beijing China"},{"name":"Tianjin Key Laboratory of Intelligent Control of Electrical Equipment TianGong University  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6017-7575","authenticated-orcid":false,"given":"Kaiyou","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Semiconductor Physics and Chip Technologies Institute of Semiconductors Chinese Academy of Sciences  Beijing China"},{"name":"Center of Materials Science and Optoelectronics Engineering University of Chinese Academy of Sciences  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,11]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.abe0722"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/s23218768"},{"key":"e_1_2_9_4_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1063\/1.1633025","article-title":"Miniature Spectroscopic Instrumentation: Applications to Biology and Chemistry","volume":"75","author":"Bacon C.
