Important results from the project
The goal of the project was to design and implement an integrated LIDAR with an absolute wavelength reference on a chip. We will achieve this goal, although with some delay. During the project, we have worked on both the absolute wavelength reference and the complete LIDAR circuit. The project has generated many new ideas and some concrete new connections that will very likely lead to new research collaborations.
Expected long term effects
LIDAR sensors provide a 3D map of their surroundings and are used for autonomous navigation. A complete LIDAR circuit on a chip will be highly useful for all autonomous vehicles, especially those with weight and power constraints, such as drones. Beyond this, we envision that the platform we have developed will have many applications within the second wave of quantum technology, which is currently advancing at a rapid pace.
Approach and implementation
Frequency-modulated continuous wave (FMCW) LIDAR is best suited for mission-critical applications due to its immunity to interference and unique ability to detect the velocity of observed objects. We have developed an integrated FMCW LIDAR circuit with an absolute wavelength reference on the chip. During the project, we have worked on both the absolute wavelength reference and the complete LIDAR circuit.
