Esteban Martínez, Óscar ; González Cano, Agustín ; Díaz Herrera, Natalia ; Navarrete Fernández, María Cruz | Optical Society of America | 2006-11-01A new concept of surface plasmon resonance fiber optic sensor is presented. By tuning the plasmon resonance to a wavelength for which the outer medium is absorptive, a significant variation of the spectral transmittance of the device is produced[...]texto impreso
Rodriguez Schwendtner, Eva María ; Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; González Cano, Agustín ; Esteban Martínez, Óscar | IEEE | 2019-05-10An advanced plasmonic sensor for high sensitivity measurement of magnetic field is presented. It is based on the combination of a SPR refractometer (doubly-deposited tapered optical fiber) with magnetic fluids used as transducers. The device is [...]texto impreso
Leite, I. ; Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; González Cano, Agustín ; Esteban Martínez, Óscar | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2011In this work we present experimental results that confirm the influence of an absorptive surrounding medium in the behavior of conventional SPR fiber sensors. It can be observed that when a plasmon resonance coincides with a wavelength absorbed [...]texto impreso
En la memoria presentada, se aborda el problema de las estructuras híbridas formadas por una fibra óptica de sección cilíndrica a la que se elimina parcialmente el revestimiento mediante un pulido lateral de la misma, junto con una estructura de[...]texto impreso
González Cano, Agustín ; Díaz Herrera, Natalia ; Navarrete Fernández, María Cruz ; Esteban Martínez, Óscar | SPIE--The International Society for Optical Engineering | 2007Although many optical fiber sensors have been proposed for chemical, environmental or biological measurements, it seems that the potential of this kind of devices has not been fully exploited. In this paper we discuss the possibilities of doubly[...]texto impreso
Navarrete Fernández, María Cruz ; Díaz Herrera, Natalia ; González Cano, Agustín ; Esteban Martínez, Óscar | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2013In this work we experimentally show how the technology of surface plasmon resonance (SPR) in doubly deposited uniform-waist tapered optical fiber sensors (DLUWTs) can be extended into the visible region (around 520 nm) by changing the thicknesse[...]texto impreso
Díaz Herrera, Natalia ; Esteban Martínez, Óscar ; Navarrete Fernández, María Cruz ; González Cano, Agustín | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2004An optical-fiber salinometer has been evaluated during a two-week measurement campaign in the Baltic Sea. The obtained results in three different tests are presented in comparison with those obtained with a standard electric CTD sonde commercial[...]texto impreso
Esteban Martínez, Óscar ; Navarrete Fernández, María Cruz ; González Cano, Agustín ; Bernabeu Martínez, Eusebio | SPIE--The International Society for Optical Engineering | 2000The degree of salinity of water is measured by determining its refractive index with a fiber-optics sensor. The physical principle of the device is the attenuation of the optical power guided by the fibre by the resonant coupling with surface pl[...]texto impreso
Díaz Herrera, Natalia ; Navarrete Fernández, María Cruz ; Esteban Martínez, Óscar ; González Cano, Agustín | IOP Publishing Ltd. | 2004-02A fibre-optic sensor has been developed for the measurement of temperature, especially of liquids. The device is conceived as part of an all-optical CTD probe for the control of the physical parameters of a marine medium. The dependence on tempe[...]texto impreso
Díaz Herrera, Natalia ; González Cano, Agustín ; Esteban Martínez, Óscar ; Navarrete Fernández, María Cruz ; Mizaikoff, Boris | Springer Science+Business Media | 2012-12A technique is proposed to extend the application of surface-plasmon-based spectroscopy into the mid-infrared spectral regime, which is of substantial interest in the field of chemical analysis and biosensing. Surface plasmons can be excited for[...]texto impreso
Esteban Martínez, Óscar ; Díaz Herrera, Natalia ; Naranjo Vega, Fernando Bernabé ; Valdueza Felip, Sirona ; Navarrete Fernández, María Cruz ; González Cano, Agustín | Elsevier Science S A | 2011-11-15In this work, an Indium Nitride (InN) dielectric overlay has been used to develop a surface plasmon resonance optical fiber sensor. Although InN is a very promising material in electronics industry, this is the first time that this kind of mater[...]texto impreso
Esteban Martínez, Óscar ; Naranjo Vega, Fernando Bernabé ; Díaz Herrera, Natalia ; Valdueza Felip, Sirona ; Navarrete Fernández, María Cruz ; González Cano, Agustín | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2011In this work, the performance of uniform-waist tapered optical fiber sensors based on SPR with Indium Nitride (InN) as dielectric layer has been experimentally studied. The obtained results show that the overall performance in terms of reliabili[...]texto impreso
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
Esteban Martínez, Óscar ; Navarrete Fernández, María Cruz ; González Cano, Agustín ; Bernabeu Martínez, Eusebio | The Optical Society Of America | 1999-09-01A fiber-optic sensor based on surface-plasmon resonance for the determination of the refractive index is used for measuring the degree of salinity of water. The transducing element consists of a multilayer structure deposited on a side-polished [...]
