Abstract: 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.

Abstract: A surface-emitting laser package comprises: a substrate; a surface-emitting laser device disposed on the substrate, and having a non-emitting area and an emitting area which includes a plurality of emitters each generating a first laser beam; a housing disposed around the surface-emitting laser device; and a diffusing part disposed on the surface-emitting laser device. The emitting area has a first width in a first direction and a second width in a second direction perpendicular to the first direction, and the second width may be greater than the first width. The diffusing part outputs the first laser beam into a second laser beam having a first angle of view in the first direction and a second angle of view in the second direction, and the first angle of view may be greater than the second angle of view.
