Abstract:
Provided are a photodetector, a manufacturing method thereof, and a lidar system. A photosensitive region of the photodetector is circular and has a diameter range of 100-300 μm. Compared with a conventional photodetector having a photosensitive region with a diameter of 50 μm, the photodetector of the present invention can have a detection range greater than 200 m, responsivity greater than 20 A/W and a dark current less than 10 nA.
