The embodiment relates to a surface emitting laser package and a light emitting device including the same. The surface-emitting laser package according to the embodiment may include a housing including a cavity, a surface-emitting laser device disposed in the cavity, and a diffusion unit disposed on the housing. The diffusion unit may include a polymer layer and a glass layer disposed on the polymer layer. The polymer layer may include a first polymer layer vertically overlapping the surface emitting laser device, and a second polymer layer not vertically overlapping the surface emitting laser device. The thickness of the first polymer layer may be thinner than the thickness of the second polymer layer.

In a surface emitting laser package, a surface emitting laser element and a substrate may be electrically connected through a diffusion part. In detail, according to the surface emitting laser package, a housing includes a step, the diffusion part is disposed at the step of the housing, and the surface emitting laser element and the substrate may be electrically connected through a connection wiring extending through the housing to correspond to the step and a conductive line disposed at one side of the diffusion part.

Surface emitting laser package

An embodiment relates to a surface emitting laser device and a light emitting device including the same. The surface emitting laser device according to the embodiment may include a first reflective layer; an active layer disposed on the first reflective layer; an active region disposed on the active layer and having an aperture and an insulation region disposed around the aperture; and a second reflective layer disposed on the active region. The second reflective layer may include a core reflective layer disposed in a position vertically corresponding to the aperture. The embodiment may include a cladding insulation layer disposed around the core reflective layer. The horizontal cross-section of the aperture may be different from the horizontal cross-section of the core reflective layer.
