Abstract
An embodiment relates to a surface-emitting laser element, a light-emitting device comprising same, and a method for manufacturing same. A surface-emitting laser element according to an embodiment may comprise: a substrate; a first reflective layer disposed on the substrate; an active layer disposed on the first reflective layer; an aperture region disposed on the active layer and including an aperture and an insulation region; and a second reflective layer disposed on the aperture region. The doping level of the aperture region may be (X+3)×XE18 (atoms/cm) A ratio (b/a) of a second minimum diameter (b) to a first maximum diameter (a) of the aperture may be [95.0−(2X/3)]% to [99.9−(X/3)]%, wherein X may be 0 to 3.
