Abstract
We report the first demonstration of on-chip cascaded stimulated Brillouin scattering (SBS). Cascaded SBS is
characterized in a 4 cm long chalcogenide (As2S3) rib waveguide where the end facet reflections provide a monolithic
Fabry–Perot (FP) resonator. The presence of the FP cavity reduces the Brillouin gain threshold, which enables
observation of cascaded SBS at reduced pump powers. We observe up to three orders of Stokes waves in the
backscattered signal at a coupled peak power of 1:34 W. Anti-Stokes waves due to four-wave mixing between
the pump and the Stokes wave were observed in the forward spectrum.
