High performance and proven quality
Meet the key requirements for automotive LiDAR systems: Reliability, performance and cost.
More than fifteen years ago the first commercial automotive LiDAR system – based on an edge-emitting, 905 nm laser by OSRAM – hit the road. Today, millions of our lasers are at work in industrial and automotive LiDAR applications, ensuring safe, reliable and high-performance operation. Based on the well-established InGaAs material system for infrared emitters, the 905 nm, edge-emitting lasers (EEL) have long mastered high-volume production and automotive grade quality requirements.
Edge-emitting, infrared lasers deliver the performance needed for LiDAR in ADAS and autonomous driving applications. Their high power density and pulse peak power allows for long-range and high resolution LiDAR systems. Thanks to low inductance EEL enable the operation with extremely short pulses and thus long detection ranges while maintaining eye-safe systems. We have demonstrated pulse lengths below 2 nanoseconds at 120 W and below 5 ns at 480 W optical power. The wavelength of 905 nm matches the spectral sensitivity of silicon-based detectors which are easily available, reliable and low cost.
All in all, 905nm EEL enable cost-effective and powerful LiDAR systems. They thus allow you to meet the cost requirements for ADAS or autonomous driving in consumer vehicles without having to make compromises on reliability and performance.
Our technology leadership advances your system
Together with our customers, we have been pioneering LiDAR applications. We developed a multi-junction technology which offered the power levels required for long detection ranges and thus enabled industry’s first automotive LiDAR system. In co-creation with the pioneers who first developed LiDAR for autonomous driving, we have continuously pushed our laser technology.
Our inventions overcome long-thought limitations. In 2019, we introduced the industry’s first automotive grade, AEC-Q102 qualified high power LiDAR lasers.
In early 2021 we invented a solution to significantly boost the achievable range with 905 nm EEL. Our wavelength stability technology increases the detection distance by 15 to 30 percent with the same laser power. Our new wavelength stability dramatically improves system efficiency: It enables lower currents for the same range. Overall systems cost decreases because no thermo-electric cooling is required. Detector signal quality improves significantly thanks to narrower optical filters. Our customer’s LiDAR systems realize detection ranges over 200m.
Our EEL deliver the kind of quality you want for an automotive safety system. We have more than ten million of these lasers in the field in automotive applications. More than ten car models feature assistance systems based on LiDAR using our devices. Altogether, these systems have seen well more than 200 billion kilometers. Not even once have they experienced any chip failures.
We are more than ready to serve a mass-market with best in class EEL for automotive LiDAR.
LiDAR applications by OSRAM OS feature a broad range of benefits. Whether it is in terms of performance, resolution, design freedom or seamless integration in greater systems. Explore the benefits that make our LiDAR technology and products unique:
- Enhancing performance & reach
Technical advancements, particularly through optimizations in chip design and package, have made it possible to significantly increase performance of LiDAR within the operating limits. In addition, parameters such as pulse lengths have also been significantly improved.
- Ensuring high-resolution
Today’s LiDAR laser chips like the »SPL DP90_3« have a much narrower emission width of 120 µm. With its optical output of 65 W at 20 A, the component is ideally suited for capturing the immediate vehicle environment, thus ensuring high-resolution images for downstream systems.
- Empowering design freedom
The current generation of the »SPL DP90_3«, for example, is characterized not only by improved beam quality but also by particularly compact dimensions. Thanks to the chip’s space-saving footprint of only 0.3 mm x 0.6 mm, extremely compact designs are possible for system manufacturers.
- Enabling seamless integration
In autumn 2019, OSRAM presented the »SPL S4L90A«, the world’s first automotive-qualified (AEC-Q102) four-channel pulse laser for LiDAR applications. The special SMT package makes system integration of the high-power lasers much easier for system developers.
