ABSTRACT
Inelastic scatterings turn out to occupy an essential place in sensing applications, since they simply require a plain optical fiber as sensing element, with no special preparation. They give rise to energy and momentum transfers with the fiber material, and make it thus possible to access material properties other than the simple linear optical response. In addition, inelastic scatterings can exist in a stimulated flavor that gives rise to dynamic couplings between all the waves involved in the interaction. This way, efficient energy transfers between optical waves can be achieved via the intercession of material vibrations to eventually generate optical amplification.
