A semiconductor vertical resonant cavity light source includes an upper mirror and a lower minor that define a vertical resonant cavity. A first active region is within the vertical resonant cavity for light generation between the upper minor and lower mirror. The vertical resonant cavity includes an inner mode confinement region and an outer current blocking region. A depleted heterojunction current blocking region (DHCBR) is within the outer current blocking region of at least one of the upper minor, lower minor, and first active region. A conducting channel within the inner mode confinement region is framed by the DHCBR. The DHCBR forces current flow into the conducting channel during operation of the light source.
