Applications using stimulated scatterings

This lecture covers various applications of stimulated scatterings in optical fibers, including power probing using stimulated Brillouin scattering, distributed Raman and Brillouin fiber sensing, slow & fast light, dynamic Brillouin gratings, and optical storage. The instructor explains the concepts of distributed sensing, scattering processes, and classification of distributed sensors based on position resolution and interaction type. Additionally, the lecture delves into optical time-domain analyzers, optical frequency-domain analyzers, coherent optical frequency-domain analyzers, and optical correlation-domain analyzers. The principles of Raman distributed sensing, Brillouin distributed sensing, and Brillouin optical time-domain analysis are also discussed, along with demonstrations of slow light phenomena.
