However, the increased requirements for flexible illumination due to sometimes overlapping specifications of two or more modalities limit the immediate availability of options to flexibly couple the same light source into different channels. This work presents two setups using incoherent and coherent sources for flexible light coupling into the individual cores of a fan-out fiber bundle. The setups use dichroic mirrors to combine the optical paths of each source into one and a rotatable mirror to control the coupling into each fiber core. Both systems show insubstantial stray light coupling and fiber crosstalk, while providing adequate output powers.<\/jats:p>","DOI":"10.1051\/jeos\/2026062","type":"journal-article","created":{"date-parts":[[2026,8,22]],"date-time":"2026-08-22T18:47:51Z","timestamp":1787424471000},"page":"70","source":"Crossref","is-referenced-by-count":0,"title":["Multiplexed light source for flexible multimodal fiber-based illumination in biomedical optical imaging"],"prefix":"10.1051","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-3760-9866","authenticated-orcid":false,"given":"\u00d6mer","family":"Atmaca","sequence":"first","affiliation":[{"name":"Institute of Applied Optics (ITO), University of Stuttgart","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anton","family":"Zimmermann","sequence":"additional","affiliation":[{"name":"Institute of Applied Optics (ITO), University of Stuttgart","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-1722-4923","authenticated-orcid":false,"given":"Markus","family":"Gro\u00dfmann","sequence":"additional","affiliation":[{"name":"Institute of Applied Optics (ITO), University of Stuttgart","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5355-722X","authenticated-orcid":false,"given":"Alois","family":"Herkommer","sequence":"additional","affiliation":[{"name":"Institute of Applied Optics (ITO), University of Stuttgart","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"250","published-online":{"date-parts":[[2026,10,6]]},"reference":[{"key":"R1","doi-asserted-by":"publisher","first-page":"69","DOI":"10.1109\/RBME.2010.2081975","volume":"3","author":"Dhawan","year":"2010","journal-title":"IEEE Rev.
