Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics
Advanced Physics Research, EarlyView.This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.
