Experimental and numerical characterization of a hybrid Fabry-Perot cavity for temperature sensing
(MDPI, 2015)
info:eu-repo/semantics/article,
A hybrid Fabry-Pérot cavity sensing head based on a four-bridge microstructured fiber is characterized for temperature sensing. The characterization of this cavity is performed numerically and experimentally in the L-band. ...
Single-longitudinal-mode dual wavelength-switchable fiber laser based on superposed fiber bragg gratings
(IEEE, 2015)
info:eu-repo/semantics/article,
n this work, a simple switchable dual-wavelength short-cavity fiber laser operating in a single-longitudinal-mode regime at room temperature and based on superposed fiber Bragg gratings is proposed and experimentally ...
Narrow-linewidth multi-wavelength random distributed feedback laser
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this work, narrow-band emission lines are generated by means of two random distributed feedback fiber laser schemes. Spectral line-widths as narrow as 3.2 pm have been measured, which significantly improves previous ...
Simultaneous measurement of strain and temperature using a single emission line
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this work, we present and demonstrate a novel sensor system for simultaneous measurement of strain and temperature through a unique combination of a long period grating (LPG) and a fiber laser based on a fiber Bragg ...
Stable multi-wavelength erbium fiber ring laser with optical feedback for remote sensing
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this work, we demonstrate a stable fiber sensing system for remote temperature measurements, where the sensing element is an array of four fiber Bragg gratings (FBGs) and sensor interrogation is achieved with a ...
Fully switchable multi-wavelength fiber lasers based on random distributed feedback for sensors interrogation
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this paper, the experimental study and characterization of a novel real-time switchable multi-wavelength fiber laser has been carried out. Two different gain materials, such as a 50 km SMF and a 2.5 km DCF fibers were ...
Optimization of the available spectrum of a WDM sensors network using a mode locked laser
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
This work experimentally proposes a new interrogation method which consists on the combination of the information given by both domains: time and frequency. On the one hand, the sensor information is obtained in the frequency ...
Real-time FFT analysis for interferometric sensors multiplexing
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this paper, a theoretical and experimental study of two interferometric sensor multiplexing schemes has been carried out by means of the fast Fourier transform (FFT) analysis. This work addresses one of the main drawbacks ...
Compound lasing fiber optic ring resonators for sensor sensitivity enhancement
(IEEE / OSA, 2015)

In this work, a new method for increasing simultaneously the sensitivity and interrogation stability of fiberoptic intensity sensors is presented. The configuration is based on a double-coupler ring resonator. On one side, ...
Simultaneous measurement of strain and temperature based on clover microstructured fiber loop mirror
(Elsevier, 2015)
info:eu-repo/semantics/article,
In this work, two all-fiber loop mirrors using a clover microstructured fiber for the simultaneous measurement of temperature and strain are presented. The sensing heads are formed by a short piece of clover microstructured ...
