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 ...
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 ...
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 ...

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 ...
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

info:eu-repo/semantics/conferenceObject,
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, ...
