The device operates in reflection mode and consists of a centimeter-long segment of properly selected PCF fusion spliced to single mode optical fibers. Two identical collapsed zones in the PCF combined with its modal properties allow high-visibility interference patterns. The interferometer is suitable for refractometric and liquid level sensing. The measuring refractive index range goes from 1.33 to 1.43 and the maximum resolution is ~1.6 \u00d7 10\u22125.<\/jats:p>","DOI":"10.3390\/s130202349","type":"journal-article","created":{"date-parts":[[2013,2,8]],"date-time":"2013-02-08T11:00:45Z","timestamp":1360321245000},"page":"2349-2358","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["High-Visibility Photonic Crystal Fiber Interferometer as Multifunctional Sensor"],"prefix":"10.3390","volume":"13","author":[{"given":"G.","family":"C\u00e1rdenas-Sevilla","sequence":"first","affiliation":[{"name":"Corning Cable Systems S.A. de C.V.
