Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

Integrated silicon nitride (SiN) waveguides offer ultra‐low propagation loss across a broad transparency window, enabling large‐scale photonic integrated circuits (PICs) for applications from LiDAR to quantum photonics. However, integrating lasers on SiN PICs remains challenging due to the large refractive‐index cont...
