A light-emitting element array according to the present technology includes: a light-emitting element group; a first wire; and a second wire. The light-emitting element group includes a plurality of first light-emitting elements and a plurality of second light-emitting elements that are arrayed in a planar manner to form a light-emitting element surface. The first wire extends in a direction parallel to the light-emitting element surface, has a region overlapping with the plurality of first light-emitting elements and a region overlapping with the plurality of second light-emitting elements as viewed from a direction perpendicular to the light-emitting element surface, is electrically connected to the plurality of first light-emitting elements, and is not electrically connected to the plurality of second light-emitting elements. The second wire extends in a direction parallel to the light-emitting element surface, has a region overlapping with the plurality of first light-emitting elements and a region overlapping with the plurality of second light-emitting elements as viewed from a direction perpendicular to the light-emitting element surface, is electrically connected to the plurality of second light-emitting elements, and is not electrically connected to the plurality of first light-emitting elements.

Light-emitting element array

The present technology provides a surface emitting laser capable of suppressing a decrease in luminous efficiency. The present technology provides a surface emitting laser including: first and second multilayer film reflectors; a plurality of active layers laminated together between the first and second multilayer film reflectors; a tunnel junction disposed between two active layers adjacent to each other in a lamination direction among the plurality of active layers; and an oxide confinement layer disposed between one active layer of the two adjacent active layers and the tunnel junction. According to the present technology, it is possible to provide a surface emitting laser capable of suppressing a decrease in luminous efficiency.
