Osram Will Launch A New Lidar Infrared Laser For Autonomous Driving
Yesterday (3), Osram announced that its new generation of LiDAR (LiDAR) infrared lasers will come out soon. The special design of the chip improves the wavelength stability of the edge emitter to a new level, thereby greatly improving the clarity and sharpness of environmental images.
LiDAR is short for Light Detection and Ranging, which uses infrared light to create accurate three-dimensional environmental maps. As a key technology to promote the development of the self-driving car industry, LiDAR, through the combination of radar and camera systems, acts as a visual sensor for cars to obtain information about the surrounding environment. The higher the quality of the visual information obtained by the detection system, the easier it is for the back-end system to process the visual information.

Image source: Osram Opto SemiconductorsIn the existing technology, infrared lasers used for LiDAR still have deviations in wavelength stability, and as the operating temperature increases, the wavelength deviation can reach up to 40 nanometers. Therefore, the “vision” of the LiDAR system will appear blurred. Currently. Osram’s new chip design can reduce the wavelength deviation to 10 nanometers, thereby greatly improving the clarity and sharpness of environmental images.
In the field of automotive applications, thanks to the newly developed chip design, the wavelength stability of edge-emitting lasers at a maximum operating temperature of 125°C can match or exceed VCSELs. In the future, this technology will be fully applied to all Osram infrared lasers.
