LiDAR (Light Detection and Ranging)

OSRAM OS – your partner for LiDAR systems:

LiDAR technology is crucial on the path to autonomous driving, since it paves the way and guides vehicles and its passengers safely through the traffic. At very short intervals, an infrared laser sends light pulses into the vehicle’s environment. When the light hits an object, it is reflected and finally registered by a sensor. The system can then calculate the distance from the light to the object and back again (»time-of-flight«) in order to initiate appropriate actions such as braking. LiDAR is therefore an indispensable technology that will contribute significantly to the mobility of tomorrow.

Depending on the applied LiDAR system and the distance of objects to be identified different degrees of the light sources EEL (»edge-emitting lasers«) and VCSEL (»vertical cavity surface emitting lasers«) are required. Only when EEL and VCSEL function complementary can the full potential of LiDAR be unleashed and the overarching goal of road safety be achieved. As an experienced innovation leader, OSRAM OS is the only player in the market that offers both – EEL and VCSEL solutions. Therefore, we are the right partner for you and your specific needs when it comes to LiDAR technology.

Our ambition – the best LiDAR solutions for you:  

No matter if LiDAR systems will be realized by VCSEL or infrared lasers, we strive to fulfill and advance our role at the forefront of LiDAR technology. By constantly expanding our LiDAR portfolio we always focus on research – all with the ultimate goal to create the best solutions. 

On VCSEL side our latest product developments include a 10 W VCSEL chip that helps our customers in the 3D sensor industry to achieve higher performance and better efficiency.

Thanks to the newly developed chip design, edge-emitting lasers (EEL) can match and even exceed the wavelength stability of VCSELs at operating temperatures of up to 125°C typical for automotive applications. This technological milestone in the development of infrared lasers allows the use of a much smaller wavelength filter on the detector - which significantly improves the signal-to-noise ratio. This technological advance has already been demonstrated in components with "triple-junctions," e.g. three light-emitting surfaces stacked one on top of the other. In future, it will be used in all Osram infrared lasers and offer enormous advantages to LiDAR system manufacturers.

Benefits

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.
