Relative humidity multi-point optical sensors system based on Fast Fourier multiplexing technique
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this paper, a new multipoint optical fiber system for relative humidity measurements based on Sn02-FP (Fabry-Pérot) sensing heads and an optical interrogator as single active device is presented and characterized. The ...
Simultaneous and quasi-independent strain and temperature sensor based on microstructured optical fiber
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this paper, a new sensor system for simultaneous and quasi-independent strain and temperature measurements is presented. The interrogation of the sensing head has been carried out by monitoring the FFT phase variations ...
Influence of saturable absorbers on fiber ring laser sensors
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this work, a fiber ring laser sensor has been employed to analyze the influence of passive Er-doped fiber acting as saturable absorber. Lasing modes of fiber ring lasers can be reduced by properly locating a saturable ...
All-fiber lasers through photonic crystal fibers
(Science Wise Publishing & De Gruyter, 2013)
info:eu-repo/semantics/article,
A review on all-fiber lasers based on photonic crystal fibers is presented. Photonic crystal fibers present improved features beyond what conventional optical fibers can offer. Due to their geometric versatility, photonic ...
Comparative study of ring and random cavities for fiber lasers
(Optical Society of America, 2014)
info:eu-repo/semantics/article,
An experimental comparison of three fiber laser structures with the same Raman gain medium is presented in order to establish the main pros and cons of each basic scheme. The first fiber laser is based on a hybrid ring–random ...
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 ...
Internal modulation of a Random fiber laser
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A characterization of a modulated random mirror laser has been experimentally carried out. Unlike conventional internally modulated fiber lasers, no distortion of the modulating frequency or self-mode-locking effects were ...
250 km ultra long remote sensor system based on a fiber loop mirror interrogated by an OTDR
(Optical Society of America, 2011)
info:eu-repo/semantics/article,
A 253 km ultra long remote displacement sensor system based on a fiber loop mirror interrogated by a commercial OTDR is proposed and experimentally demonstrated. The use of a fiber loop mirror increases the signal to noise ...
