A vertical cavity surface emitting laser, includes a substrate, a lower mirror stack adjacent the substrate, an active region operably coupled to the lower mirror stack, and an upper mirror operably coupled to the active region, opposite the lower mirror. The lower mirror active region and upper mirror arranged in a vertical stack to form a laser. A plurality of spaced apart regions of increased refractive index which extend in a vertical direction at least partially through the vertical stack to promote single mode confinement in the stack.
