✦ Synopsis

A vertical microcavity laser structure with an active layer of Stranski-Krastanow quantum dots was fabricated for the first time. The microcavity consists of an InGaAs quantum dot layer grown by MOCVD, located between two A1As/Alo.2Gao.sAs distributed Bragg-reflector mirrors. The length of the microcavity was 42(2 = 884 nm). The cavity effect was evidenced by the difference of the PL linewidths of samples with and without the cavity.

An analytical approach to the calculation of the spontaneous emission of a quantum dot or other "active area" embedded into a spherical Bragg microcavity has been developed. Spontaneous emission spectra have been calculated.

We developed a new scheme using modulated stacking of self-assembled InAs QDs on InP(3 1 1)B substrates with strain compensation to fabricate QDs in order to expand the potential bandwidths of QD active regions. A highly stacked QD structure was fabricated by the strain-compensation technique with n
