November 14, 2025, Shanghai, China — ams OSRAM (SIX: AMS), a global leader in lighting and sensing innovation, today announced a new five-junction edge-emitting laser, marking a significant leap in LiDAR system performance. This product integrates five vertically stacked emitter layers within a single-chip structure, delivering higher peak power alongside significantly reduced power consumption, thereby enabling longer detection range and improved energy efficiency.
Compared to previous-generation three-junction lasers, the innovative stacked architecture of the new five-junction laser not only substantially extends detection range but also reduces heat generation through lower resistive losses, simplifying thermal management design. This characteristic makes it particularly suitable for space-constrained automotive electronic architectures. Furthermore, the laser incorporates wavelength stabilization technology, ensuring consistent measurement performance even under fluctuating temperature conditions and providing reliable environmental perception for autonomous driving systems.
'With superior detection range, stability, and ease of integration, the five-junction laser empowers customers to build high-performance, low-power LiDAR systems, accelerating the deployment of autonomous driving technology,' said Tobias Hofmeier, Product Marketing Manager at ams OSRAM.
As LiDAR technology sees increasing application in autonomous taxis, delivery vehicles, and Advanced Driver-Assistance Systems (ADAS), this laser, by enhancing detection accuracy and range, has the potential to push the speed limits of autonomous driving, unlocking new possibilities for high-level assistance on highways. The product is currently available in bare-die form, offering greater design flexibility and integration potential for system developers.
