The approach relies on selective air-hole infiltration in otherwise defect-free PCSs. We show that using this method we can design ultrahigh-Q microcavities, with Q~106. Numerical calculations indicate a large number of high-Q modes with high sensitivity, which are ideal for simultaneous, multi-parameter refractive index-based sensing.<\/jats:p>","DOI":"10.3390\/s130303262","type":"journal-article","created":{"date-parts":[[2013,3,8]],"date-time":"2013-03-08T11:22:13Z","timestamp":1362741733000},"page":"3262-3269","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Reconfigurable, Defect-Free, Ultrahigh-Q Photonic Crystal Microcavities for Sensing"],"prefix":"10.3390","volume":"13","author":[{"given":"Snjezana","family":"Tomljenovic-Hanic","sequence":"first","affiliation":[{"name":"School of Physics, University of Melbourne, Parkville, VIC 3010, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"De Sterke","sequence":"additional","affiliation":[{"name":"ARC Centre of Excellence for Ultrahigh-bandwidth Devices for Optical Systems,  and School of Physics, University of Sydney, Sydney, NSW 2006, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,3,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"449","DOI":"10.1038\/nphoton.2007.141","article-title":"Spontaneous-emission control by photonic crystals and nanocavities","volume":"1","author":"Noda","year":"2007","journal-title":"Nat.
