Integrated Si photonics offers a promising solution to address the rising demand for data processing capability and energy efficiency spurred by AI and high-performance computing. However, the integration of on-chip lasers has been hindered by the inherent indirect bandgap of Si, limiting integration density, production efficiency, and cost-effectiveness. In this work, we overcome this challenge through the heterogeneous integration of quantum dots (QDs) with Si-on-insulator based photonic integrated circuits. Our objective is to advance the post-Moore performance scaling of electronic systems and explore the potential applications of this integration in quantum communication and optical computation.
