The results show that the roundtrip phase change in the ring resonator due to the temperature change is the major reason for the transmission variation. The performance of the temperature sensor is also discussed and it is shown that for a waveguide-ring resonator with the resonator radius around 5 mm and waveguide-ring gap of 500 nm which gives a footprint around 140 \u00b5m2, the temperature sensitivity at the order of 10\u22122 K can be achieved with the input power of 100 mW within the measurement sensitivity limit of a practical optical detector.<\/jats:p>","DOI":"10.3390\/s110201992","type":"journal-article","created":{"date-parts":[[2011,2,7]],"date-time":"2011-02-07T11:12:06Z","timestamp":1297077126000},"page":"1992-2000","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Compact on-Chip Temperature Sensors Based on Dielectric-Loaded Plasmonic Waveguide-Ring Resonators"],"prefix":"10.3390","volume":"11","author":[{"given":"Thomas  B.","family":"Andersen","sequence":"first","affiliation":[{"name":"Institute of Technology and Innovation, University of Southern Denmark, Niels Bohrs Alle 1, DK-5230 Odense M, Denmark"}]},{"given":"Zhanghua","family":"Han","sequence":"additional","affiliation":[{"name":"Institute of Technology and Innovation, University of Southern Denmark, Niels Bohrs Alle 1, DK-5230 Odense M, Denmark"}]},{"given":"Sergey  I.","family":"Bozhevolnyi","sequence":"additional","affiliation":[{"name":"Institute of Technology and Innovation, University of Southern Denmark, Niels Bohrs Alle 1, DK-5230 Odense M, Denmark"}]}],"member":"1968","published-online":{"date-parts":[[2011,2,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2959","DOI":"10.1063\/1.1305516","article-title":"Review of temperature measurement","volume":"71","author":"Childs","year":"2000","journal-title":"Rev.
