    Abstract: A detection apparatus includes a light emitting unit including a first light emitting region that has at least one light emitting element and radiates light to a first radiation region and a second light emitting region that has at least one light emitting element and radiates light to a second radiation region, a drive unit that drives the light emitting unit, and a detection unit that detects an object based on a time until light radiated from the light emitting unit is reflected by the object and is received, in which the first radiation region is positioned outside with respect to the second radiation region, and an amount of light radiated from the first light emitting region is greater than an amount of light radiated from the second light emitting region.

    Abstract: A light-emitting component includes: a substrate; plural light-emitting elements that are disposed on the substrate and that emit light in a direction intersecting with a surface of the substrate; and plural thyristors that are stacked on the plural light-emitting elements and that are turned ON to drive the corresponding light-emitting elements so that the light-emitting elements emit light or an amount of light emitted from the light-emitting elements is increased. Each of the plural light-emitting elements includes a current confinement region which is oxidized via a hole provided in a multilayer structure. The multilayer structure is constituted by a corresponding light-emitting element and a corresponding thyristor.

    Abstract: A surface emitting laser element array includes multiple two-dimensionally arranged surface-emitting laser element groups each including multiple surface-emitting laser elements. The multiple surface-emitting laser element groups are drivable independently of each other. The multiple surface-emitting laser element groups are arranged in an arrangement region such that the number of surface-emitting laser element groups arranged in a first direction is larger than the number of surface-emitting laser element groups arranged in a second direction perpendicular to the first direction. An irradiation region irradiated with light emitted from the multiple surface-emitting laser element groups has a shape elongated in the first direction. The arrangement region in which the multiple surface-emitting laser element groups are arranged has an aspect ratio closer to 1:1 than the irradiation region.
