Title:
SURFACE EMITTING LASER PACKAGE
Document Type and Number:
WIPO Patent Application WO/2019/035653
Kind Code:
A1
Abstract:
A surface emitting laser package comprises: a substrate; a surface emitting laser diode 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 diode; and a diffusing part disposed on the surface emitting laser diode. 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.
