Coupled-core fiber Bragg gratings for low-cost sensing
Flores Bravo, José Ángel; Madrigal, Javier; Zubia Zaballa, Joseba Andoni; Sales, Salvador; Villatoro Bernardo, Agustín Joel (Nature Research, 2022)[EN] Sensors based on Bragg gratings inscribed in conventional single mode fibers are expensive due to the need of a sophisticated, but low-speed, interrogation system. As an alternative to overcome this issue, in this ... -
Optical fiber interferometer for temperature-independent refractive index measuring over a broad range
Flores Bravo, José Ángel; Illarramendi Leturia, María Asunción ; Zubia Zaballa, Joseba Andoni; Villatoro Bernardo, Agustín Joel (Elsevier, 2021-07)The present work relates to manufacturing of a simple interferometric optical fiber refractometer that features broad refractive index measuring range without ambiguity. The device consists of a cylindrical polymer cavity ... -
Sensitivity magnification of an interferometric optical fiber sensor with a length-linked virtual reference
Zornoza Indart, Ander; Flores Bravo, José Ángel; Zubia Zaballa, Joseba Andoni; Villatoro Bernardo, Agustín Joel (Elsevier, 2023-12)Here, it is proposed an alternative to magnify the sensitivity of a single optical fiber interferometric sensor up to two orders of magnitude. The method consists of fabricating the sensing interferometer with a specific ... -
Simultaneous Sensing of Refractive Index and Temperature With Supermode Interference
Flores Bravo, José Ángel; Fernández Bello, Rubén ; Antonio López, José Enrique; Zubia Zaballa, Joseba Andoni; Schülzgen, Axel; Amezcua Correa, Rodrigo; Villatoro Bernardo, Agustín Joel (IEEE, 2021-11-15)[EN]In general, a sensor is used to monitor a single parameter only, and in many cases, a reference sensor is necessary to compensate the effect of temperature. Here, we demonstrate that a single supermode interferometer ...
