Here, a CMOS-compatible silicon nitride (SiN) visible light photonic integrated circuits (PICs) platform is employed to successfully demonstrate an ultracompact RGB (de)multiplexer, featuring a footprint as small as 86 \u00d7 2.3\u2009\u00b5m\n                    <jats:sup>2<\/jats:sup>\n                    . Leveraging a novel, to the best of our knowledge, dual-segmented multimode waveguide design, the device achieves a low insertion loss of ~1\u20132\u2009dB at target wavelengths and sets the stage for monolithic integration of laser sources on the same PIC chip. This breakthrough further paves the way for the development of integrated, miniaturized CMOS-compatible RGB light engines offering superior brightness, high resolution, and a wide field-of-view. We anticipate that our design can contribute significantly to the development of immersive AR\/VR\/MR display technology, while simultaneously extending its impact into sensing and visible light communication applications.\n                  <\/jats:p>","DOI":"10.1364\/ol.601014","type":"journal-article","created":{"date-parts":[[2026,6,8]],"date-time":"2026-06-08T13:00:10Z","timestamp":1780923610000},"page":"3749","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Ultracompact RGB (de)multiplexer based on a silicon nitride dual-segmented MMI"],"prefix":"10.1364","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8887-0980","authenticated-orcid":true,"given":"Farhan","family":"Ali","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05f950310","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Imec"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruno","family":"Figeys","sequence":"additional","affiliation":[{"name":"Imec"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oksana","family":"Shramkova","sequence":"additional","affiliation":[{"name":"Imec"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roelof","family":"Jansen","sequence":"additional","affiliation":[{"name":"Imec"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xavier","family":"Rottenberg","sequence":"additional","affiliation":[{"name":"Imec"},{"name":"ULB, Ecole Polytechnique de Bruxelles"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Gehlhaar","sequence":"additional","affiliation":[{"name":"Imec"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4019-5979","authenticated-orcid":true,"given":"Jan","family":"Genoe","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05f950310","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Imec"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,6,30]]},"reference":[{"key":"ol-51-13-3749-R1","doi-asserted-by":"publisher","first-page":"216","DOI":"10.1038\/s41377-021-00658-8","type":"journal-article","volume":"10","author":"Xiong","year":"2021","journal-title":"Light Sci.
