The micro-size suspended core is created by chemical etching a photonics crystal fiber, of which the cladding has a micrometer-spaced, hexagonal array of air holes. The sensing head is fabricated by chemical etching a short section of photonics crystal fiber spliced with a single mode fiber. The temperature sensing characteristic of the interferometer has also been demonstrated and a sensitivity 14.3 pm\/\u00b0C is obtained.<\/jats:p>","DOI":"10.3390\/s140916808","type":"journal-article","created":{"date-parts":[[2014,9,11]],"date-time":"2014-09-11T02:22:24Z","timestamp":1410402144000},"page":"16808-16815","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Intrinsic Fabry-Perot Interferometeric Sensor Based on Microfiber Created by Chemical Etching"],"prefix":"10.3390","volume":"14","author":[{"given":"Ruohui","family":"Wang","sequence":"first","affiliation":[{"name":"School of Physics, Northwest University, 229 Taibai Road, Xi'an 710069, China"}]},{"given":"Xueguang","family":"Qiao","sequence":"additional","affiliation":[{"name":"School of Physics, Northwest University, 229 Taibai Road, Xi'an 710069, China"}]}],"member":"1968","published-online":{"date-parts":[[2014,9,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1016\/j.yofte.2006.03.004","article-title":"Recent progress in fiber-optic extrinsic Fabry-Perot interferometric sensors","volume":"12","author":"Rao","year":"2006","journal-title":"Opt.
