The increasing demand for efficient, compact, and scalable photonic systems has driven research to overcome silicon’s nonlinear limitations at higher power levels (> 10 mW). In this work, we present a hybrid III-V on SOI external cavity laser structure that integrates silicon double-ring-resonators with a loop mirror at the back-side of the cavity and an interlayer coupler at the front-side to transition to a silicon nitride (SiN) photonic integrated circuit (PIC). This asymmetric design leverages the complementary strengths of both platforms: silicon's compact size and relatively lower tuning power and SiN's wide bandgap and negligible nonlinear absorption at the output, allowing the system to achieve high power levels with reduced nonlinear loss.
