Distributed forward stimulated Brillouin scattering measurement using broadband BOTDR

Luc Thévenaz, Simon Adrien Zaslawski, Zhisheng Yang, Sheng Wang

Brillouin optical time-domain reflectometry is used to perform distributed forward stimulated Brillouin scattering (FSBS) measurements. This configuration suppresses the need for an additional frequency scanning to evaluate the local Brillouin peak gain wh ...

Design rules for optimizing unipolar coded Brillouin optical time-domain analyzers

Luc Thévenaz, Zhisheng Yang, Marcelo Alfonso Soto Hernandez, Simon Adrien Zaslawski, Zonglei Li

The performance of unipolar unicolor coded Brillouin optical time-domain analysis (BOTDA) is evaluated based on both Simplex and Golay codes. Four major detrimental factors that limit the system performance, including decoded-gain trace distortion, coding ...

Boosting the performance of distributed optical fiber sensors based on adaptive decoder

Luc Thévenaz, Zhisheng Yang, Simon Adrien Zaslawski, Sheng Wang, Jian Wu

An adaptive decoder is proposed to derive the fiber single-pulse response. This experimentally simple technique simultaneously improves the measurement time and the noise level, boosting to an uncommon degree the overall performance of distributed fiber se ...
