Random fiber lasers: application to fiber optic sensors networks
(IEEE, 2017)
info:eu-repo/semantics/conferenceObject,
Recently, random mirrors have been proposed as a method to create fiber laser cavities. This kind of cavity is based on cooperative Rayleigh scattering, which is generated along a fiber due to the material inhomogeneities ...
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 ...
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 ...
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 ...
L-band multiwavelength single-longitudinal mode fiber laser for sensing applications
(IEEE / OSA, 2012)
info:eu-repo/semantics/article,
In this work, a novel single-longitudinal-mode (SLM) four-wavelength laser configuration for sensing applications in the L-band is proposed and experimentally demonstrated. The sensor system presented here is based on ring ...
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 ...
Stability comparison of two ring resonator structures for multiwavelength fiber lasers using highly doped Er-fibers
(IEEE / OSA, 2009)
info:eu-repo/semantics/article,
An experimental comparison of stability between two different fiber laser topologies is carried out. The lasers are based on ring resonators that include highly-doped Er-fibers. Both topologies use fiber Bragg grating ...
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 ...
