Light detection and ranging (LiDAR) has gained significant traction over the last years, mainly driven by the automotive, consumer electronics and industrial automation sectors. Photonic integrated circuits (PICs) allow integrating all the required photonic building blocks (laser source, solid-state beamsteering, photodetectors, routing and switching structures) on a single Si/SiN chip using CMOS-compatible foundry processes. This platform is particularly interesting for developing frequency-modulated continuous-wave (FMCW) LiDAR engines operating at short-wave infrared (SWIR) wavelengths. Such emerging fully-integrated LiDAR systems promise to reduce size, weight, power and cost, while increasing reliability and performance. In this talk, we will summarize imec’s main research directions on PIC-based solid-state LiDAR modules, with a focus on different solid-state beamsteering approaches.
Dr. Marcus Dahlem received his PhD in electrical engineering from MIT in 2011. He joined imec in 2018 as a principal member of technical staff, and is currently the program manager for optical 3D sensing, where he focuses on developing solid-state LiDAR systems for automotive. He has co-authored over 110 peer-reviewed publications. Prior to joining imec, he was an associate professor and the director of the Center of Excellence on Integrated Photonics at the Khalifa University of Science and Technology in Abu Dhabi. He also worked at the IBM Zurich Research Laboratory, and at the Institute for Systems and Computer Engineering of Porto.
