Díaz Herrera, Natalia ; Esteban Martínez, Óscar ; Navarrete Fernández, María Cruz ; González Cano, Agustín ; Benito Peña, María Elena ; Orellana Moraleda, Guillermo | Elsevier Sci. Ltd. | 2011-08We present the results of a chemical attack on the optical fiber surface previous to the deposition of the double layer (metal plus dielectric) in Double-layer uniform-waist tapered fibers (DLUWTs) used for the development of SPR sensors. It is [...]texto impreso
Díaz Herrera, Natalia ; Esteban Martínez, Óscar ; Navarrete Fernández, María Cruz ; Le Haitre, Michel ; González Cano, Agustín | IOP Publishing Ltd. | 2006-08We have successfully proved the feasibility of an optical salinity meter for marine applications in a two-week measurement campaign, carried out for the realization of in situ salinity measurements in seawater. An optical instrument (optode), in[...]texto impreso
Rodriguez Schwendtner, E. ; Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; Esteban Martínez, Óscar ; González Cano, Agustín | Elsevier Science S A | 2016-02We present a new technique for exciting and collecting fluorescence with all-fiber devices, consisting of two different tapered fibers, a microfiber used as illuminating source and a polymer optical fiber where a fluorophore has been deposited a[...]texto impreso
Viegas, Diana Catarino das Neves ; Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; González Cano, Agustín ; Santos , Jose Luis ; Araújo, Fernanda Mendes | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2011A miniature fiber Bragg grating strain rosette is presented. The proposed design is made possible through the development of low curvature radius lossless tapers, thus offering advantages in miniaturization of the rosette configuration. We repor[...]texto impreso
Díaz Herrera, Natalia ; González Cano, Agustín ; Viegas, Diana Catarino das Neves ; Santos, Jose Luis ; Navarrete Fernández, María Cruz ; Esteban Martínez, Óscar | SPIE--The International Society for Optical Engineering | 2010It is shown how the design possibilities offered by double-layer uniform-waist tapered optical fibers (DLUWTs) permit to move the wavelength detection range to adapt the response of the sensors to varied conditions. In particular, we have obtain[...]texto impreso
Esteban Martínez, Óscar ; Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; González Cano, Agustín ; Bernabeu Martínez, Eusebio | International Society Offshore & Polar Engineers | 2004A new type of multiparametric optical sensor system for in-situ measurements in seawater was tested under real conditions. Central to the system is an underwater core instrument (CI) which contains light sources and a multichannel spectrometer w[...]texto impreso
González Cano, Agustín ; Bueno Guillén, Francisco Javier ; Esteban Martínez, Óscar ; Díaz Herrera, Natalia ; Navarrete Fernández, María Cruz | The Optical Society Of America | 2005-02-01Novel devices consisting of uniform-waist tapered optical fibers with asymmetric double-layer (metal plus dielectric) depositions have been recently proposed as refractive-index sensors. We study the properties of light transmission by use of th[...]texto impreso
Rodriguez Schwendtner, E. ; Díaz Herrera, Natalia ; Navarrete Fernández, María Cruz ; González Cano, Agustín ; Esteban Martínez, Óscar | Elsevier | 2017-09-01We present a new sensor based on the combination of Surface Plasmon Resonance (SPR) with magneto-refractive materials. We use doubly-deposited uniform-waist tapered optical fibers (DLUWTs), that have shown their good performance and versatility [...]texto impreso
González Cano, Agustín ; Navarrete Fernández, María Cruz ; Esteban, Óscar ; Díaz Herrera, Natalia | MDPI | 2014A review of the surface plasmon resonance (SPR) transducers based on tapered fibers that have been developed in the last years is presented. The devices have proved their good performance (specifically, in terms of sensitivity) and their versati[...]texto impreso
Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; González Cano, Agustín ; Esteban Martínez, Óscar | Springer Science+Business Media | 2010-03The resonance of surface plasma waves in metallic layers is a strongly polarization-dependent phenomenon by the very nature of the physical effect responsible of that resonance. This implies the necessity of polarization-controlling elements to [...]texto impreso
Díaz Herrera, Natalia ; González Cano, Agustín ; Viegas, Diana Catarino das Neves ; Santos, Jose Luis ; Navarrete Fernández, María Cruz | Elsevier Sci. Ltd. | 2010-04-08Experimental results are shown demonstrating that multiple surface plasma waves can be excited in optical fibres at the 1.5 ?m optical communications region for the range of refractive indices of aqueous media using doubly deposited tapered fibr[...]texto impreso
Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; González Cano, Agustín ; Esteban Martínez, Óscar ; Leite, Ivo | Elsevier Science S A | 2011-12-15Conventional surface plasmon resonance (SPR) fiber sensors show selective behavior when resonance wavelengths are tuned to absorption peaks of the surrounding medium, as it is experimentally shown and evaluated in this paper by using a doubly-de[...]texto impreso
Bueno Guillén, Francisco Javier ; Esteban Martínez, Óscar ; Díaz Herrera, Natalia ; Navarrete Fernández, María Cruz ; González Cano, Agustín | The Optical Society Of America | 2004-03-10A novel, to our knowledge, device based on a tapered optical fiber with a double-layer deposition including a metallic media is presented, and its properties are studied. The main novelty of the device consists of the introduction of a dielectri[...]texto impreso
