A vertical-cavity surface-emitting laser comprises one or more semiconductor epitaxial phase-shifting mesa layers that are adapted to provide optical mode confinement, and that are further embedded between semiconductor epitaxial materials with a conductivity type that is substantially the same as the phase-shifting mesa layers. The laser further includes reverse-biased p-n junction materials adjacent to the epitaxial phase-shifting mesa layers that laterally confine electrically injected current to the phase-shifting mesa layers through formation of resistive material outside the phase-shifting mesa layers.
