Time-domain Brillouin scattering assisted by diffraction gratings [PDF]
Physical Review B, 2017 Absorption of ultrashort laser pulses in a metallic grating deposited on a transparent sample launches coherent compression/dilatation acoustic pulses in directions of different orders of acoustic diffraction. Their propagation is detected by the delayed

Time-domain Brillouin Scattering as a Local Temperature Probe in Liquids [PDF]
MRS Advances, 2018 We present results of time-domain Brillouin scattering (TDBS) to determine the local temperature of liquids in contact to an optical transducer. TDBS is based on an ultrafast pump-probe technique to determine the light scattering frequency shift caused ...

Crystalline-like ordering of 8CB liquid crystals revealed by time-domain Brillouin scattering [PDF]
The Journal of Chemical Physics, 2020 We demonstrate that time-domain Brillouin scattering (TDBS), a technique based on an ultrafast pump-probe approach, is sensitive to phase transitions and apply it to the study of structural changes in 8CB liquid crystals at different temperatures across the isotropic, nematic, smectic, and crystalline phases.

Characterization of the Noise Induced by Stimulated Brillouin Scattering in Distributed Sensing
Sensors, 2020 The excess noise due to stimulated Brillouin scattering (SBS) in gain and loss-based Brillouin optical time-domain analyzers (BOTDA) has been investigated theoretically and experimentally for the first time to the best of our knowledge.

Monitoring in the Physical Channels of Optical Access Networks
Proceedings of the International Conference on Applied Innovations in IT, 2023 This research concerns the issues of monitoring in the physical channels optical access networks. This is relevant because automated diagnostic and monitoring systems in passive optical networks (PONs) are not available at the moment. The authors discuss
