Title:
SURFACE EMITTING LASER PACKAGE AND LIGHT EMITTING DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/216724
Kind Code:
A1
Abstract:
An embodiment relates to a surface emitting laser package and a light emitting device comprising same. The surface emitting laser package according to an embodiment may comprise: a housing including a cavity; a surface emitting laser element disposed in the cavity; and a diffusion part disposed on the housing. The diffusion part may include a polymer layer, and a glass layer disposed on the polymer layer. The polymer layer may include: a first polymer layer which vertically overlaps the surface emitting laser element; and a second polymer layer which does not vertically overlap the surface emitting laser element. The first polymer layer may have a thickness thinner than that of the second polymer layer.
