Optimization of sensitivity in Long Period Fiber Gratings with overlay deposition.
TL;DR: The deposition of an overlay of higher refractive index than the cladding in a Long Period Fiber Grating permits to improve the sensitivity to ambient refractiveIndex changes in a great manner, and henceforward fast shifts of the resonance wavelength of the attenuations bands in the transmission spectrum are studied.
Journal ArticleDOI
Femtomolar Detection by Nanocoated Fiber Label-Free Biosensors.
Francesco Chiavaioli,Pablo Zubiate,Ignacio Del Villar,Carlos R. Zamarreño,Ambra Giannetti,Sara Tombelli,Cosimo Trono,Francisco J. Arregui,Ignacio R. Matias,Francesco Baldini +9 more
TL;DR: Repeated experiments confirm a big leap in performance thanks to the capability to detect femtomolar concentrations in human serum, improving the detection limit by 3 orders of magnitude when compared with other fiber-based configurations.
Journal ArticleDOI
Design rules for lossy mode resonance based sensors
Ignacio Del Villar,Miguel Hernaez,Carlos R. Zamarreño,P. Sanchez,Carlos Fernández-Valdivielso,Francisco J. Arregui,Ignacio R. Matias +6 more
TL;DR: Lossy mode resonances can be obtained in the transmission spectrum of cladding removed multimode optical fiber coated with a thin-film and basic rules of design, which enable the selection of the best parameters for each specific sensing application, are indicated in this work.

TL;DR: Lossy-mode resonance (LMR)-based optical sensing technology has emerged in the last two decades as a nanotechnological platform with very interesting and promising properties as mentioned in this paper, which enables one to tune the position of the resonance in the optical spectrum, to excite the resonance with both transverse electric (TE) and transverse magnetic (TM) polarized light.
Journal ArticleDOI
Deposition of overlays by electrostatic self-assembly in long-period fiber gratings
TL;DR: A theoretical model for analyzing a multilayer cylindrical waveguide is presented that permits the phenomenon to be understood and predicted and results are corroborated with experimental ones obtained by electrostatic self-assembly.
