Compensation of nonlocal effects induced by the extinction ratio of pump pulses in Brillouin optical time-domain analysis sensors
Mariñelarena Ollacarizqueta, Jon
; Iribas Pardo, Haritz ; Urricelqui Polvorinos, Javier ; Loayssa Lara, Alayn (Optical Society of America, 2019)
Artículo / Artikulua 
We demonstrate a technique to compensate the nonlocal effects that appear in Brillouin optical time-domain analysis sensors when pump pulses with limited extinction ratio are deployed. These recently discovered nonlocal ... -
Cyclic coding for Brillouin optical time-domain analyzers using probe dithering
Iribas Pardo, Haritz ; Loayssa Lara, Alayn ; Sauser, Florian; Llera, Miguel; Le Floch, Sébastien (Optical Society of America, 2017)
Artículo / Artikulua
We study the performance limits of mono-color cyclic coding applied to Brillouin optical time-domain analysis (BOTDA) sensors that use probe wave dithering. BOTDA analyzers with dithering of the probe use a dual-probe-sideband ... -
Humidity sensor based on Bragg gratings developed on the end facet of an optical fiber by sputtering of one single material
Ascorbe Muruzabal, Joaquín ; Corres Sanz, Jesús María ; Arregui San Martín, Francisco Javier ; Matías Maestro, Ignacio (MDPI, 2017)
Artículo / Artikulua
The refractive index of sputtered indium oxide nanocoatings has been altered just by changing the sputtering parameters, such as pressure. These induced changes have been exploited for the generation of a grating on the ... -
Optimization in nanocoated D-shaped optical fiber sensors
Del Villar, Ignacio ; Zubiate Orzanco, Pablo ; Ruiz Zamarreño, Carlos ; Arregui San Martín, Francisco Javier ; Matías Maestro, Ignacio (Optical Society of America, 2017)
Artículo / Artikulua
Nanocoated D-shaped optical fibers have been proven as effective sensors. Here, we show that the full width at half minimum (FWHM) of lossy mode resonance can be reduced by optimizing the nanocoating width, thickness and ... -
Sensitivity enhancement in low cutoff wavelength long-period fiber gratings by cladding diameter reduction
Del Villar, Ignacio ; Partridge, Matthew; Rodríguez Rodríguez, Wenceslao Eduardo; Fuentes Lorenzo, Omar ; Socorro Leránoz, Abián Bentor ; Díaz Lucas, Silvia ; Corres Sanz, Jesús María ; James, Stephen; Tatam, Ralph (MDPI, 2017)
Artículo / Artikulua
The diameter of long-period fiber gratings (LPFGs) fabricated in optical fibers with a low cutoff wavelength was be reduced by hydrofluoric acid etching, enhancing the sensitivity to refractive index by more than a factor ... -
Sensitivity optimization with cladding-etched long period fiber gratings at the dispersion turning point
Del Villar, Ignacio ; Cruz, José Luis; Socorro Leránoz, Abián Bentor ; Corres Sanz, Jesús María ; Matías Maestro, Ignacio (Optical Society of America, 2016)
Artículo / Artikulua
This work presents a refractive index sensor based on a long period fiber grating (LPFG) made in a reduced cladding fiber whose low order cladding modes have the turning point at large wavelengths. The combination of ... -
Virtual FBGs using saturable absorbers for sensing with fiber lasers
Rodríguez Cobo, Luis; Pérez Herrera, Rosa Ana ; Quintela, M. A.; Ruiz Lombera, Rubén; López-Amo Sáinz, Manuel ; López Higuera, José Miguel (MDPI, 2018)
Artículo / Artikulua
The spectral narrowing of Fiber Bragg Gratings (FBGs) introduced by unpumped Er-doped fiber (EDF) was analyzed for fiber lasers (FL). Owing to spatial hole burning (SHB), the spectral response of a virtual FBG can be ...
