ABSTRACT:
A surface-emitting type semiconductor laser includes: a first mirror; an active layer formed above the first mirror; a second mirror formed above the active layer; and a current constricting section formed above or below the active layer, wherein the second mirror has a plurality of concave sections arranged within a plane perpendicular to a light emission direction, and a light confining region surrounded by the concave sections is formed inside a region surrounded by the current constricting section as viewed in a plan view.
