ABSTRACT:
Provided is a surface emitting laser which can maintain a fundamental transverse mode to obtain higher power while higher-order transverse mode oscillations are suppressed, and a method of manufacturing the surface emitting laser. The surface emitting laser includes: an aperture portion to be a path for injecting a current to an active layer; a current confinement region provided in the vicinity of the aperture portion; and a current injection region which is provided on an opposite side to a light output side with respect to the active layer therebetween, in which a current injection path in the current injection region has a smaller diameter than the aperture portion.
