Low noise dual-wavelength erbium fiber laser in single-longitudinal-mode operation
(Springer, 2012)
info:eu-repo/semantics/article,
A new stable dual-wavelength fiber-ring laser
based on erbium-doped fiber amplification is reported. The
laser is based on ring resonators and employs fiber Bragg
gratings to select the operation wavelengths. The ...
Simultaneous measurement of humidity and vibration based on a microwire sensor system using Fast Fourier Transform technique
(IEEE, 2016)
info:eu-repo/semantics/article,
This paper presents a new sensor system for vibration and relative humidity measurements based on its interaction with the evanescent field of a microwire. The interrogation of the sensing head is carried out by monitoring ...
An in-reflection strain sensing head based on a Hi-Bi photonic crystal fiber
(MDPI, 2013)
Artículo / Artikulua,
A photonic crystal fiber-based sensing head is proposed for strain measurements. The sensor comprises a Hi-Bi PCF sensing head to measure interferometric signals in-reflection. An experimental background study of the sensing ...
Remote (250 km) fiber Bragg grating multiplexing system
(MDPI, 2011)
Artículo / Artikulua,
We propose and demonstrate two ultra-long range fiber Bragg grating (FBG) sensor interrogation systems. In the first approach four FBGs are located 200 km from the monitoring station and a signal to noise ratio of 20 dB ...
Simultaneous measurement of humidity and vibration based on a nanowire sensor system using Fast Fourier Transform technique
(IEEEOptical Society of America, 2016)
Artículo / Artikulua,
This paper presents a new sensor system for vibration and relative humidity measurements
based on its interaction with the evanescent field of a microwire. The interrogation of the
sensing head is carried out by monitoring ...
Single-longitudinal mode laser structure based on a very narrow filtering technique
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A narrow filtering technique based on the spectral overlapping of
two uniform FBGs and applied to obtain a Single Longitudinal Mode
(SLM) laser is proposed and demonstrated in this work. The two FBGs are
spectrally ...
SnO2-MOF-Fabry-Pérot humidity optical sensor system based on Fast Fourier transform technique

In this paper, a new sensor system for relative humidity measurements based on a SnO2 sputtering deposition on a microstructured optical fiber (MOF) low-finesse Fabry-Pérot (FP) sensing head is presented and characterized. ...
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 ...
Compound lasing fiber optic ring resonators for sensor sensitivity enhancement
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
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, ...
Switchable erbium doped fiber ring laser system for temperature sensors multiplexing
(IEEE, 2013)
info:eu-repo/semantics/article,
In this paper a proof of concept of a switchable erbium doped fiber ring laser (EDFRL) system, demonstrated for temperature sensors multiplexing, was carried out showing a high linearity and a sensitivity of 1.55 GHz/°C. ...
