http://soest.hawaii.edu/HIGP/Faculty/zinin/Zi-Brillouin.html WebStimulated Brillouin scattering(SBS) is originated by the interaction between the signal photons and the traveling sound waves, also called acoustic phonons(Boyd, 1992). It is just like that when you blow air into an open-ended tube: A sound wave may be generated. Because of the SBS, the signal lightwave is modulated by the traveling sound wave.
