Abstract
Spontaneous emission control has been achieved in GaAs/AlGaAs quantum well lasers by the use of Distributed Bragg microcavity perpendicular to the quantum wells. The room temperature emission is inhibited whilst below 130 K there is an enhancement. These changes to the spontaneous emission process directly effect the threshold current producing a 25% reduction at room temperature. Theoretical modeling of the lasers is in agreement with the experimental results and highlights the effect of the microcavity on the field-dipole interaction.
