Fully switchable multi-wavelength fiber lasers based on random distributed feedback for sensors interrogation

Bravo Acha, Mikel

; Miguel Soto, Verónica de

; Ortigosa Cayetano, Amaia; López-Amo Sáinz, Manuel

(IEEE / OSA, 2015) Artículo / Artikulua

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 ...

Random DFB fiber laser for remote (200 km) sensor monitoring using hybrid WDM/TDM

; Bravo Acha, Mikel

; López-Amo Sáinz, Manuel

(IEEE, 2016) Artículo / Artikulua

In this paper, a random distributed feedback fiber laser is proposed as a multiplexing scheme for ultralong range measurements (up to 200 km). Optical fiber sensors are time and wavelength multiplexed overcoming one of the ...

Spectral shadowing suppression technique in phase-OTDR sensing based on weak fiber Bragg grating array

Miguel Soto, Verónica de

; Jason, Johan; Kurtoglu, Deniz; López-Amo Sáinz, Manuel

; Wuilpart, Marc (Optical Society of America, 2019) Artículo / Artikulua

A postprocessing procedure is presented to suppress spectral shadowing in phase-OTDR sensing systems based on a weak fiber Bragg grating array. A complete theoretical analysis of the interfering signals has been carried ...

Study of optical fiber sensors for cryogenic temperature measurements

; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe; López-Amo Sáinz, Manuel

(MDPI, 2017) Artículo / Artikulua

In this work, the performance of five different fiber optic sensors at cryogenic temperatures has been analyzed. A photonic crystal fiber Fabry-Pérot interferometer, two Sagnac interferometers, a commercial fiber Bragg ...

Ultra-long (290 km) remote interrogation sensor network based on a random distributed feedback fiber laser

Miguel Soto, Verónica de

; Leandro González, Daniel

; López-Amo Sáinz, Manuel

(Optical Society of America, 2018) Artículo / Artikulua

In this work, an interferometric sensor has been interrogated 290 km away from the monitoring station, reaching the longest distance in fiber optic sensing up to date. This has been attained by employing a double-pumped ...
