Abstract
A semiconductor vertical light source includes an upper mirror and a lower mirror. An active region is between the upper and lower mirror. The light source includes an inner mode confinement region and outer current blocking region. The outer current blocking region includes a common epitaxial layer that includes an epitaxially regrown interface which is between the active region and upper mirror, and a conducting channel including acceptors is in the inner mode confinement region. The current blocking region includes a first impurity doped region with donors between the epitaxially regrown interface and active region, and a second impurity doped region with acceptors is between the first doped region and lower mirror. The outer current blocking region provides a PNPN current blocking region that includes the upper mirror or a p-type layer, first doped region, second doped region, and lower mirror or an n-type layer.
