As significant progress towards ADAS level 3 consumer vehicles is made, more automotive OEMs are looking at LiDAR technology. We are seeing cost-driven LiDAR approach without sacrificing performance: size, location, eye safety and reliability are still key design targets. To meet those stringent requirements, a practical and scalable approach to photonic integration is required. Significant progress has been made toward commercialization of LiDAR systems for early deployment in autonomous shuttles, robotaxis, and high-end, ADAS level 2-3 consumer vehicles. We will discuss photonic solutions used in automotive LiDAR applications with focus on the light sources which meet the design challenges for next-gen, wide-scale, extended range 3D sensing applications.
