Abstract

We report the first demonstration of on-chip cascaded stimulated Brillouin scattering (SBS). Cascaded SBS is characterized in a 4cm 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 1.34W. Anti-Stokes waves due to four-wave mixing between the pump and the Stokes wave were observed in the forward spectrum.

FP cavity enhanced cascaded SBS principle: the pump field E p (solid) experiences multiple reflections and generates back- and forward propagating S1 wave E S 1 (--). The S1 waves then undergo multiple reflections and gain and pump the generation of E S 2 .
