Abstract:
Disclosed is a surface emitting laser module including a surface emitting laser element formed in a semiconductor substrate and having a surface emitting laser array that emits light in a direction perpendicular to a surface of the semiconductor substrate; a package having a region in which the semiconductor substrate is provided; and a metal cap having a cylindrical part formed of metal, the cylindrical part having a transparent substrate on one side thereof and a bottom part on the other side thereof bonded to the package. The transparent substrate is provided in the metal cap in such a manner as to be inclined with respect to the semiconductor substrate, the package has a metal part at a bonding part thereof bonded to the metal cap, and the metal part and the metal cap are bonded together by welding.
