Abstract

Reduction of laser threshold in an electrically pumped vertical cavity laser is the consequence of interpositioning of an electrode layer intermediate the active, photon producing region, and at least one of the two Distributed Bragg Reflectors defining the laser cavity. The advance is a consequence of the lowered pump circuit resistance due to elimination of one or both DBRs - in particular, to elimination of the p-doped DBR - from the pump circuit.
