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 ...
Multiwavelength Raman fiber lasers using Hi-Bi photonic crystal fiber loop mirrors combined with random cavities
(IEEE / OSA, 2011)
info:eu-repo/semantics/article,
Different multiwavelength Raman fiber lasers based on a hybrid cavity set-up are proposed. The lasing schemes are based in highly birefringent photonic crystal fiber loop mirrors combined with random cavities. The Hi-Bi ...
Slow-light and enhanced sensitivity in a displacement sensor using a lossy fiber-based ring resonator
(IEEE / OSA, 2013)
info:eu-repo/semantics/article,
Along the last years, much debate has been done on the efficiency of slow-light phenomena in order to enhance lightmatter interactions, especially for sensing purposes. This improvement could be key to develop more compact ...
Concrete beam bending test monitorization using a high strain fiber optic sensor
(IEEE / OSA, 2012)
info:eu-repo/semantics/article,
In this work the development of an 'eight-shape' fiber optic sensor for high strain measurement is experimentally demonstrated. This strain sensor is interrogated using a commercial optical time domain reflectometer through ...
46-km-long Raman amplified hybrid double-bus network with point and distributed Brillouin sensors
(IEEE, 2012)
info:eu-repo/semantics/article,
We experimentally demonstrate a 46-km hybrid network that combine point and distributed Brillouin sensors. The proposed sensor network multiplexes low-cost intensity point sensors based on fiber-optic tapers, which are ...
Optical fiber bus protection network to multiplex sensors: experimental validation of self-diagnosis
(IEEE, 2012)
info:eu-repo/semantics/article,
The experimental demonstration of a resilient wavelength division multiplexed (WDM) fiber bus network to interconnect sensors is reported. The network recovers operation after failures and it performs 'self-diagnosis', the ...
Resilient amplified double ring optical networks to multiplex optical fibre sensors
(IEEE / OSA, 2009)
info:eu-repo/semantics/article,
We report the experimental demonstration of two configurations of an amplified optical fibre double ring network for the multiplexing of sensors. The networks are designed to be inherently resilient to fibre failures because ...
Frequency modulated continuous wave system for optical fiber intensity sensors with optical amplification
(IEEE, 2009)
info:eu-repo/semantics/article,
We report on the use of erbium doped fiber (EDF) amplification to enhance a frequency modulated continuous wave (FMCW) technique for referencing optical intensity sensors located between two Bragg grating structures. The ...
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. ...
