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 ...
Ultrahigh-sensitivity sensors based on thin-film coated long period gratings with reduced diameter, in transition mode and near the dispersion turning point
(Optical Society of America, 2015)
Artículo / Artikulua,
The mode transition and the dispersion turning point have been
explored for optimization of thin-film coated long period fiber gratings
during the last years. In this work and additional parameter, the cladding
diameter, ...
