Abstract
Brillouin-Mandelstam scattering is the strongest optomechanical effect in waveguides and optical fibers. It gives access to the domain of acoustic waves which follow other guiding rules and are sensitive to different parameters of the material such as pressure or temperature. This opens the opportunity to – on the one hand – modulate and process optical signals via mechanical vibrations which can be shaped by the design and material of the optoacoustic waveguides and – on the other hand – gain an insight into material properties and environmental changes. In this talk, experimental results on two topics will be presented.
