For the demultiplexing of the communication channels, a multichannel diffractive optical element (DOE) is proposed, being matched with the used vortex beams. The considered approach may be realized without digital processing of the output images, but only based on the numbers of informative diffraction orders, similar to sorting. The system is implemented based on two spatial light modulators (SLMs), one of which forms a multiplexed signal on the transmitting side, and the other implements a multichannel DOE for separating the vortex beams on the receiving side. The stability of the communication channel to atmospheric interference and the crosstalk between the channels are investigated.<\/jats:p>","DOI":"10.3390\/s21092988","type":"journal-article","created":{"date-parts":[[2021,4,25]],"date-time":"2021-04-25T02:12:57Z","timestamp":1619316777000},"page":"2988","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":70,"title":["Spatial-Light-Modulator-Based Multichannel Data Transmission by Vortex Beams of Various Orders"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6765-4373","authenticated-orcid":false,"given":"Svetlana N.","family":"Khonina","sequence":"first","affiliation":[{"name":"IPSI RAS-Branch of the FSRC \u201cCrystallography and Photonics\u201d RAS, 443001 Samara, Russia"},{"name":"Department of Technical Cybernetics, Samara National Research University, 443086 Samara, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergey V.","family":"Karpeev","sequence":"additional","affiliation":[{"name":"IPSI RAS-Branch of the FSRC \u201cCrystallography and Photonics\u201d RAS, 443001 Samara, Russia"},{"name":"Department of Technical Cybernetics, Samara National Research University, 443086 Samara, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0829-4886","authenticated-orcid":false,"given":"Muhammad A.","family":"Butt","sequence":"additional","affiliation":[{"name":"Department of Technical Cybernetics, Samara National Research University, 443086 Samara, Russia"},{"name":"Institute of Microelectronics and Optoelectronics, Warsaw University of Technology, Koszykowa 75, 00-662 Warszawa, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5448","DOI":"10.1364\/OPEX.12.005448","article-title":"Free-space information transfer using light beams carrying orbital angular momentum","volume":"12","author":"Gibson","year":"2004","journal-title":"Opt.
