Lasers have made a tremendous impact on our world – they are essential to diverse fields such as optical communications, remote sensing, manufacturing, and medicine. At the same time, photonic integrated circuits have allowed unprecedented advances in optical systems for Department of Defense (DoD) applications, including LiDAR, signal processing, chip-scale optical clocks, gyros, and data transmission. However, these two technologies today are limited by the incompatibility of the materials used to create them – silicon photonics are easy to manufacture but are poor light emitters while compound semiconductors enable efficient emitters but are difficult to scale for complex integrated circuits.
