Journal ArticleDOI
Optimization of Sensors Based on Multimode Interference in Single-Mode–Multimode–Single-Mode Structure
TL;DR: In this paper, a single-mode-multimode-single-mode (SMS) structure with a complex refractive index thin-film was proposed to shift the optical spectrum.
Journal ArticleDOI
Fiber-Optic Immunosensor Based on an Etched SMS Structure
Abian B. Socorro,Enrique Santamaría,Joaquín Fernández-Irigoyen,Ignacio Del Villar,Jesus M. Corres,Francisco J. Arregui,Ignacio R. Matias +6 more
TL;DR: In this article, a novel and high sensitive anti-IgG biosensor based on multimode interference induced through a singlemode-multimode-single-mode (SMS) optical fiber structure is developed.
Journal ArticleDOI
Resonances in coated long period fiber gratings and cladding removed multimode optical fibers: a comparative study
Ignacio Del Villar,Carlos R. Zamarreño,Miguel Hernaez,Francisco J. Arregui,Ignacio R. Matias +4 more
TL;DR: Two optical fiber devices have been coated in parallel: a long period fiber grating (LPFG) and a cladding-removed multimode optical fiber (CRMOF); a lossy-mode-resonance (LMR) is generated in the same wavelength range of the LPFG attenuation bands analyzed.
Journal ArticleDOI
Fringe generation with non-uniformly coated long-period fiber gratings.
Ignacio Del Villar,Francisco J. Arregui,Ignacio R. Matias,Andrea Cusano,D. Paladino,Antonello Cutolo +5 more
TL;DR: The spectral characteristics of non-uniform symmetrically ring shaped coatings deposited on long-period fiber gratings (LPFGs) have been theoretically and experimentally investigated and provides a valid technological platform for the development of advanced photonic devices for sensing and telecommunication applications.
Journal ArticleDOI
(INVITED)Nanocoated fiber label-free biosensing for perfluorooctanoic acid detection by lossy mode resonance
Giulia Moro,Giulia Moro,Francesco Chiavaioli,Stefano Liberi,Pablo Zubiate,Ignacio Del Villar,Alessandro Angelini,Karolien De Wael,Francesco Baldini,Ligia Maria Moretto,Ambra Giannetti +10 more
TL;DR: In this article, the potential of a label-free lossy mode resonance (LMR) assisted optical platform based on nanocoated fibers for the detection of small molecules, such as perfluorooctanoic acid (PFOA), was investigated.
