Díaz Herrera, Natalia ; Viegas, Diana Catarino das Neves ; Jorge, Pedro A. S. ; Araújo, Francisco Manuel Moita ; Santos, Jose Luis ; Navarrete Fernández, María Cruz ; González Cano, Agustín | Elsevier Science S A | 2010-01-29In this work a new configuration of a refractometric sensor for aqueous solutions based on the combination of surface plasmon resonance (SPR) with fibre Bragg gratings (FBG) is presented. Two FBGs are selected having reflection maxima in each si[...]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
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[...]
