The main driver of cost for SS-OCT systems is, however, the price of the source. Here we show a low-cost alternative swept source that uses a thermally tuned vertical-cavity surface-emitting laser (VCSEL) at 850\u2005nm. Its center wavelength can be tuned by adjusting the operating temperature through modulation of the injection current. At 2 kHz sweep rate, the depth range of the system was 5\u2005cm, with a sensitivity roll-off of under \u22123\u2005dB across this range. The system achieved a sensitivity of 97\u2005dB with a sample beam power of 0.3\u2005mW and an axial resolution of 50\u2005\u00b5m in air. To demonstrate the system performance\n                    <jats:italic>in vivo<\/jats:italic>\n                    , an eye of a healthy volunteer was measured, and full-eye scans were acquired at 25 and 50 kHz from the cornea to the retina. Based on our results, we believe that this technology can be used as a cost-effective alternative OCT for point-of-care diagnostics.\n                  <\/jats:p>","DOI":"10.1364\/ol.489050","type":"journal-article","created":{"date-parts":[[2023,5,11]],"date-time":"2023-05-11T08:00:27Z","timestamp":1683792027000},"page":"3079","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Thermally tuned VCSEL at 850\u2005nm as a low-cost alternative source for full-eye SS-OCT"],"prefix":"10.1364","volume":"48","author":[{"given":"Milana","family":"Kendrisic","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05n3x4p02","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Medical University Vienna"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladislav","family":"Agafonov","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05n3x4p02","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Salas","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05n3x4p02","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Medical University Vienna"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenzo","family":"Ferrara","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05n3x4p02","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Medical University Vienna"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Niederleithner","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05n3x4p02","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hemma","family":"Resch","sequence":"additional","affiliation":[{"name":"Vienna General Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan","family":"Steiner","sequence":"additional","affiliation":[{"name":"Vienna General Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clemens","family":"Vass","sequence":"additional","affiliation":[{"name":"Vienna General Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wolfgang","family":"Drexler","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05n3x4p02","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rainer A.","family":"Leitgeb","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05n3x4p02","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Medical University Vienna"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2023,6,1]]},"reference":[{"key":"ol-48-11-3079-R1","doi-asserted-by":"publisher","first-page":"340","DOI":"10.1364\/OL.22.000340","volume":"22","author":"Chinn","year":"1997","journal-title":"Opt.
