Stimulated Brillouin scattering (SBS) is an important nonlinear effect in optical fibers and waveguides that has been traditionally exploited for high-sensitivity distributed sensing, coherent lasers and gyroscopes. Recent advances in nanofabrication led to the extensive growth of SBS research. The ability to generate SBS in nanoscale devices has opened numerous opportunities for photonic integration, resulting in on-chip Brillouin lasers, microwave generation, Brillouin cooling and quantum optomechanics. In this paper we briefly describe principles of inelastic Brillouin scattering and review our recent developments in optical signal manipulation and lasing using on-chip SBS.
