Volume 15, Issues 5-6, October-December 2009, Pages 477-482||Abstract:||A series of surface plasmonic fibre devices were fabricated by depositing multiple thin coatings on a lapped section of a standard single mode telecoms fibre forming a D-shaped section and then inscribing a grating-type structure using UV light. The coatings consisted of base coatings of semi-conductor (germanium) and dielectric (silicon dioxide) materials, followed by different metals. These fibre devices showed high spectral refractive index sensitivity with high coupling efficiency in excess of 40 dB for indices in the aqueous regime and below, with estimated index sensitivities of Δλ/Δn = 90–800 nm from 1 to 1.15 index range and Δλ/Δn = 1200–4000 nm for refractive indices from 1.33 to 1.39.||URI:||http://ktisis.cut.ac.cy/handle/10488/1120||ISSN:||1068-5200||DOI:||http://dx.doi.org/10.1016/j.yofte.2009.09.002||Rights:||© 2009 Elsevier Inc.||Type:||Article|
