Abstract: This application pertains to the technical field of LiDAR, and discloses a phased array emission apparatus, a LiDAR, and an automated driving device. The phased array emission apparatus includes an edge coupler, an optical combiner, and a phased array unit. An output end of the edge coupler is connected to an input end of the optical combiner, and an output end of the optical combiner is connected to an input end of the phased array unit. The edge coupler is configured to input and couple a first optical signal. The optical combiner is configured to transmit, to the phased array unit, the first optical signal coupled by the edge coupler. The phased array unit is configured to split the first optical signal into several first optical sub-signals and emit the first optical sub-signals. In the foregoing method, coupling efficiency can be improved, thereby meeting a low-loss requirement.
