Brillouin optical time-domain analysis sensor assisted by Brillouin distributed amplification of pump pulses
(Optical Society of America, 2015)
Artículo / Artikulua,
We demonstrate the extension of the measurement range of
Brillouin optical time-domain analysis (BOTDA) sensors using a distributed
Brillouin amplifier (DBA). The technique is based on injecting a DBA
pump wave in the ...
Sources of noise in Brillouin optical time-domain analyzers
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
This paper presents a thorough study of the different sources of noise affecting Brillouin optical time-domain analyzers (BOTDA), providing a deep insight into the understanding of the fundamental limitations of this kind ...
Mitigation of modulation instability in Brillouin distributed fiber sensors by using orthogonal polarization pulses
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
A technique based on the use of orthogonally-polarized pulses is proposed to mitigate the detrimental impact of modulation
instability on Brillouin distributed fiber sensors. While the theoretical underpinnings of the ...
Polarization diversity scheme for BOTDA sensors based on a double orthogonal pump interaction
(IEEE, 2015)
Artículo / Artikulua,
We introduce a Brillouin optical time domain analysis (BOTDA) sensor deploying a novel polarization diversity technique based on the use of two orthogonal pump pulses which simultaneously interact with a phase modulated ...
Overcoming non-local effects and Brillouin threshold limitations in Brillouin optical time domain sensors
(IEEE, 2015)
Artículo / Artikulua,
We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis
(BOTDA) sensor that is able to operate with a probe power larger than the Brillouin threshold of the
deployed sensing fiber ...
