In Plastic Optical Fiber (POF) realized in PMMA there are different influences of design parameters on the performance, as both sensitivity and SNR are concerned. In particular, the SNR, for different refractive index values of the analyte, in a 250 \u03bcm diameter POF is greater than the one in 1,000 \u03bcm diameter POF. On the other hand, the sensitivity, for the same refractive index values of the analyte, in a 1,000 \u03bcm diameter POF is greater than the one in a 250 \u03bcm diameter POF. The results of an experimental analysis demonstrating the above behavior are reported.<\/jats:p>","DOI":"10.3390\/s130100721","type":"journal-article","created":{"date-parts":[[2013,1,7]],"date-time":"2013-01-07T11:07:53Z","timestamp":1357556873000},"page":"721-735","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":102,"title":["Performance Comparison of Two Sensors Based on Surface Plasmon Resonance in a Plastic Optical Fiber"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7769-0984","authenticated-orcid":false,"given":"Nunzio","family":"Cennamo","sequence":"first","affiliation":[{"name":"Department of Information Engineering, Second University of Naples, Via Roma 29, 81031 Aversa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Davide","family":"Massarotti","sequence":"additional","affiliation":[{"name":"Department of Physical Sciences, University of Naples \"Federico II\", via Cinthia, Naples 80126, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ramona","family":"Galatus","sequence":"additional","affiliation":[{"name":"Grup Optoelectronica si Componente Optice Integrate, Universitatea Tehnica, Cluj-Napoca 400114, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Conte","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, Second University of Naples, Via Roma 29, 81031 Aversa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luigi","family":"Zeni","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, Second University of Naples, Via Roma 29, 81031 Aversa, Italy"},{"name":"CNR-IREA, via Diocleziano 328, 80124 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,1,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"528","DOI":"10.1007\/s00216-003-2101-0","article-title":"Present and future of surface plasmon resonance biosensors","volume":"377","author":"Homola","year":"2003","journal-title":"Anal.
