The increasing demand for high pixel acquisition rates in the fields of augmented reality, autonomous driving, and robotics has led to a growing interest solid-state beam scanning solutions that do not rely on moving parts. As result, modern photonics been driving development passive steering technology meet these demands. Recently demonstrated imagers based focal plane arrays, nanophotonic metasurfaces, optical phased arrays have enabled unprecedented resolutions measurement speeds. However, parallelization >100 lasers detectors, which successfully implemented commercial time-of-flight sensors, widely adopted approaches. In this work, we demonstrate both inertia-free parallel light detection ranging (LiDAR) with microresonator frequency combs. We use 40 independent channels continuously scanned comb operated chaotic regime combination dispersive elements perform random modulation LiDAR 2D steering.
