Here, we demonstrate a nonlinear-integrated photonic platform that integrates Ge 28 Sb 12 Se 60 chalcogenide waveguides with multi-project wafer (MPW) silicon waveguides, enabling an efficient four-wave mixing (FWM) nonlinear parametric process. The nondegenerate FWM nonlinear power threshold of the hybrid-integrated photonic platform is as low as 0.16 mW. By synergistically leveraging the advantages of both optical materials, this work offers a promising avenue for the development of large-scale integrated nonlinear photonic platforms.
