Abstract :
We demonstrate the fabrication of a vertical microcavity laser structure with an active layer of Stranski-Krastanow quantum dots. The microcavity consists of an InGaAs quantum dot layer grown by MOCVD, located between two AlAs/Al0.2Ga0.8As distributed Bragg-reflector mirrors. The length of the microcavity was 1 λ(λ=1007 nm). Very narrow linewidths of the spontaneous PL-emission was observed as an clear evidence of the cavity effect. The PL-linewidth of reference samples that were grown without a cavity proves to be significantly broader
