Osram's new generation of LiDAR infrared lasers is coming soon, opening a new "horizon" for autonomous driving

     Osram has announced the arrival of its next generation of LiDAR infrared lasers, which are specially designed to increase the wavelength stability of the edge emitter to a new level, thereby greatly improving the sharpness and sharpness of environmental images.

     LiDAR, short for Light Detection and Ranging, is a technology that uses infrared light to create accurate three-dimensional maps of the environment. LiDAR is a key technology driving the development of the autonomous vehicle industry, through the combination of radar and camera systems, together acting as a visual sense of the car 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.

     At the state of the art, the infrared lasers used for LiDAR still have deviations in wavelength stability, and as the operating temperature increases, the wavelength deviation can be up to 40 nanometers, which causes the "vision" of the LiDAR system to become blurred. Osram's new chip design can reduce the wavelength deviation to 10 nanometers, which greatly improves the sharpness and sharpness of environmental images.

     In automotive applications, thanks to Osram's newly developed chip design, the wavelength stability of the edge-emitting laser can match or even exceed that of the VCSEL, even at operating temperatures up to 125°C. This not only marks a new stage in the development of infrared laser technology, but also means that it is possible to use smaller filters on the detector, which greatly improves the signal-to-noise ratio. In addition, its technological advancements have been tested and proven by "three-junction" structural elements, such as three light-emitting surfaces stacked on top of each other. In the future, this technology will be applied to all of OSram's infrared lasers, which will also bring great advantages to LiDAR system manufacturers.
