Abstract: This application discloses a frequency modulated continuous wave LiDAR and an autonomous driving device. The LiDAR includes a light source module, a silicon photonic chip and a refraction module, and the silicon photonic chip includes a light splitting module, a coupling module and multiple transceiving units.
