Stimulated Brillouin scattering (SBS) is a nonlinear optical process that is mediated by an acoustic wave. SBS has shown many interesting applications, including signal processing, sensing, and the creation of narrow-linewidth laser
sources. One big challenge in the field is unlocking the effect in a mature, densely integrated photonic platform. In this thesis we describe ways to unlock enhanced SBS in silicon nitride, a well-established platform. So far, the Brillouin gain coefficients measured in this platform have been 0.1 m−1W−1. We show that SBS can be enhanced by multiple orders of magnitude, and demonstrate the first applications of SBS in this platform.
