The sensor is based on a cascade of three microstructured optical fibers (MOFs). In the first one a suitable cascade of long period gratings is designed into the core. A single mode intermediate and a rare-earth activated Fabry-Perot optical cavity are the other two sensor MOF sections. An exhaustive theoretic feasibility investigation is performed employing computer code. The complete set-up for temperature monitoring can be obtained by utilizing only a low cost pump diode laser at 980 nm wavelength and a commercial optical power detector. The simulated sensitivity S = 315.1 \u03bcW\/\u00b0C and the operation range \u0394T = 100 \u00b0C is good enough for actual applications.<\/jats:p>","DOI":"10.3390\/s151229770","type":"journal-article","created":{"date-parts":[[2015,11,30]],"date-time":"2015-11-30T10:57:24Z","timestamp":1448881044000},"page":"29855-29870","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Electromagnetic Modelling of Fiber Sensors for Low-Cost and High Sensitivity Temperature Monitoring"],"prefix":"10.3390","volume":"15","author":[{"given":"William","family":"Scarcia","sequence":"first","affiliation":[{"name":"Department of Electrical and Information Engineering, Politecnico di Bari, via E.
