Nos vamos a sumergir en el origen de uno de los símbolos culturales más importantes del mundo occidental, el Partenón de Atenas, y veremos la evolución que ha tenido a lo largo de los veinticinco siglos que lleva dominando la capital... more
A temperature and strain optical fiber transducer and its optimal design are presented. The hybrid structure is composed of two Fiber Bragg Gratings (FBG) in a fused taper. Using the same phase mask one of the FBG is written outside of... more
A civil structure monitoring system based on fiber Bragg grating technology is presented. A complete set of new transducers, both for concrete and steel monitoring, is designed, fabricated, and successfully checked both in laboratory and... more
The prestressing force is transferred to the concrete during the slack period of precast concrete structures fabrication. To contribute to a better understanding of the armor compliant behaviors during the mentioned process, a custom... more
Una respuesta espectral arbitraria de una red de difracción en fibra óptica (RDFO) se puede conseguir por medio de la suma de las contribuciones de diferentes subRDFOs concatenadas. Estas son grabadas en serie, sin saltos de fase, usando... more
During the slack period of precast concrete structures fabrication, the prestressing force is transferred, by adhesion to concrete being the armor compliant behaviors, up today, a still pending matter. To contribute to a better... more
En este artículo se presenta un sistema sensor de temperatura basado en un laser de efecto Brillouin en fibra óptica. La onda Stokes generada tras el proceso de scattering se hace resonar en una cavidad laser que combina ganancia... more
In order to obtain an acoustic waves sensor network a lot of interferometer transducers must be multiplexed. The use of Fibre Bragg Grating (FBG)-based interferometer allows the applications of Wavelength Division Multiplexing (WDM)... more
The resulting index profile of a uniform Fiber Bragg Grating (FBG) determines the amplitudes of its first and second diffraction order wavelengths. A controlled UV writing process can be done for optimizing the reflecting powers of both... more
Se presenta el diseño, optimización, implementación y comprobación practica de un transductor de deformación y temperatura basado en redes de difracción en fibra óptica y fibras estrechadas. Usando una única mascara de fase se graban dos... more
The measures of UV induced refractive index changes in different photosensitive fibres with a interferometric method is presented.
This paper reports the realization of a wavelength demultiplexing using plastic optical fibers and diffraction grating. This device can have applications in communications of short distance as well as applications in optical sensors.

We present the application of photonic crystal fibers (PCF) as sensors. For it will be studied the influence of the structural parameters in the fiber (period and hole diameter) with respect to its sensitivity. The effective index will be... more
El Grupo de Ingeniería Fotónica de la Universidad de Cantabria se caracteriza por focalizar sus esfuerzos investigadores en la resolución de problemáticas no resueltas o insuficientemente solventadas. Para ello, utiliza conceptos,... more
En los ultimos anos se ha venido incrementando el uso de sensores opticos en multitud de campos (quimica, ingenieria civil, biomedicina, etc). Este tipo de sensores presentan ciertas ventajas respecto a sensores convencionales como es el... more
