Such a fiber design enables the increase in the optical sensor capacity as well as extending the sensing length with a single optical fiber while preserving the spatial sensing resolution. The method uses a multicore fiber with differently doped fiber cores and, therefore, enables a selective grating inscription. The concept can be applied in a draw tower inscription process for an efficient production of sensing networks. Along with the general concept, the paper discusses the specific preparation of the fiber-based sensing component and provides experimental results showing the feasibility of such a sensing system.<\/jats:p>","DOI":"10.3390\/s22103837","type":"journal-article","created":{"date-parts":[[2022,5,20]],"date-time":"2022-05-20T00:18:11Z","timestamp":1653005891000},"page":"3837","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Composed Multicore Fiber Structure for Extended Sensor Multiplexing with Fiber Bragg Gratings"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9837-8308","authenticated-orcid":false,"given":"Ravil","family":"Idrisov","sequence":"first","affiliation":[{"name":"Leibniz Institute of Photonic Technology, 07745 Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9669-290X","authenticated-orcid":false,"given":"Adrian","family":"Lorenz","sequence":"additional","affiliation":[{"name":"Leibniz Institute of Photonic Technology, 07745 Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manfred","family":"Rothhardt","sequence":"additional","affiliation":[{"name":"Leibniz Institute of Photonic Technology, 07745 Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hartmut","family":"Bartelt","sequence":"additional","affiliation":[{"name":"Leibniz Institute of Photonic Technology, 07745 Jena, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"107082","DOI":"10.1016\/j.optlastec.2021.107082","article-title":"Optical fiber sensing for marine environment and marine structural health monitoring: A review","volume":"140","author":"Min","year":"2021","journal-title":"Opt.
