Abstract
The present embodiment relates to a single semiconductor light-emitting element including a plurality of light-emitting portions each of which is capable of generating light of a desired beam projection pattern and a method for manufacturing the semiconductor light-emitting element. In the semiconductor light-emitting element, an active layer and a phase modulation layer are formed on a common substrate layer, and the phase modulation layer includes at least a plurality of phase modulation regions arranged along the common substrate layer. The plurality of phase modulation regions are obtained by separating the phase modulation layer into a plurality of places after manufacturing the phase modulation layer, and as a result, the semiconductor light-emitting element provided with a plurality of light-emitting portions that have been accurately aligned can be obtained through a simple manufacturing process as compared with the related art.
