Abstract

Embodiments relate to a surface-emitting laser device and a light-emitting device including the same. A surface-emitting laser device according to an embodiment includes: a first reflective layer and a second reflective layer; and an active region disposed between the first reflective layer and the second reflective layer, wherein the first reflective layer includes a first group first reflective layer and a second group first reflective layer, and the second reflective layer includes a first group second reflective layer and a second group second reflective layer. The first group second reflective layer may include: a second-first reflective layer having a first aluminum concentration; a second-second reflective layer having a second aluminum concentration higher than the first aluminum concentration and disposed on one side of the second-first reflective layer; and a second-third reflective layer having a third aluminum concentration which varies from the first aluminum concentration to the second aluminum concentration and disposed between the second-first reflective layer and the second-second reflective layer. A second conductive doping concentration of the second-third reflective layer may be higher than a second conductive doping concentration of the second-first reflective layer or the second-second reflective layer.
