Using a discrete Fourier transform-based Brillouin optical time-domain
reflectometer, the observation of distributed high-order acoustic longi-
tudinal modes with a 20 m spatial resolution are reported. A dispersion
shifted fibre is investigated and [...]

Thanks to a double-frequency phase modulation scheme, we report a vector Brillouin optical time-domain analyzer
(BOTDA). This BOTDA has a high immunity level to noise, and it features a phase spectrogram capability. It is well
suited for complex si [...]

We report the observation of anti-crossings between hybrid-mode acoustic phonons in an axially-varying photonic crystal fiber. Our experimental results are analyzed using an electrostriction theory which reveals strong coupl [...]
