Swept optical single sideband modulation for spectral measurement applications using stimulated Brillouin scattering
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We propose a technique for the generation of broadband optical single sideband modulated signals. The technique is based on optically processing an optical double sideband signal using stimulated Brillouin scattering effect. ...
Orthogonally polarized optical single sideband modulation for microwave photonics processing using stimulated Brillouin scattering
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We present a novel technique to generate orthogonally polarized
optical single sideband modulated signals. The modulation scheme is based
on all optical stimulated Brillouin scattering processing of the optical carrier
of ...
Effects of pump pulse extinction ratio in Brillouin optical time-domain analysis sensors
(Optical Society of America, 2017)
info:eu-repo/semantics/article,
We report on two previously unknown non-local effects that have been found to impair
Brillouin optical time-domain analysis (BOTDA) sensors that deploy limited extinction ratio
(ER) pump pulses. The first one originates ...
Long-range hybrid network with point and distributed Brillouin sensors using Raman amplification
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We propose a novel concept for hybrid networks that combine
point and distributed Brillouin sensors in a cost-effective architecture that
also deploys remote distributed Raman amplification to extend the sensing
range. A ...
Enhancement of the dynamic range in slope-assisted coherent brillouin optical time-domain analysis sensors
(IEEE, 2017)
Artículo / Artikulua,
We present two techniques that provide an extension of the dynamic range of coherent Brillouin optical time-domain analysis (BOTDA) sensors for dynamic measurements. This type of BOTDA sensors rely on self-heterodyne ...
Non-local effects in Brillouin optical time-domain analysis sensors
(MDPI, 2017)
Artículo / Artikulua,
Brillouin optical time-domain analysis (BOTDA) sensors have great potential to provide distributed measurements of temperature and strain over large structures with high spatial resolution and measurement precision. However, ...
Brillouin optical time-domain analyzer for extended sensing range using probe dithering and cyclic coding
(SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We present an enhanced performance Brillouin optical time-domain analysis sensor that uses dual probes waves with optical frequency modulation and cyclic coding. The frequency modulation serves to increase the probe power ...

Cyclic coding for Brillouin optical time-domain analyzers using probe dithering
(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 ...
Enhancement of signal-to-noise ratio in Brillouin optical time domain analyzers by dual-probe detection
(SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a simple technique to enhance the signal-to-noise ratio (SNR) in Brillouin optical time-domain analysis sensors by the addition of gain and loss processes. The technique is based on the shift of the pump ...
