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
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
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
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
Rodriguez Schwendtner, Eva María ; González Cano, Agustín ; Díaz Herrera, Natalia ; Navarrete Fernández, María Cruz ; Esteban Martínez, Óscar | Elsevier | 2018-09-01The importance of Surface Plasmon Resonance (SPR)-based devices in the field of chemical and biological sensing and the expectations created in terms of sensitivity and resolution impose the necessity of developing an adequate methodology for th[...]texto impreso
Esteban Martínez, Óscar ; Navarrete Fernández, María Cruz ; González Cano, Agustín ; Bernabeu Martínez, Eusebio | Elsevier Sci. Ltd. | 2000-03In this work we present an application of a simple quasi-geometrical model to analyze the behavior of compound waveguide structures used as fiber-optic sensors. This theoretical model is based on the adjustment of the parameters of the structure[...]texto impreso
