Opis:: We report on MBE growth and study of optical and structural properties of (ZnSe/MgS)/ZnCdSe distributed Bragg reflectors with λ=520 nm and R$\text{}_{max}$=97%. The samples were grown pseudomorphically on GaAs substrate using ZnS as a sulphur source. Scanning electron microscopy, X-ray diffraction, and optical measurements showed good optical and structural characteristics of the Bragg reflectors.

Opis:: We report on molecular beam epitaxy of CdSe/CdMgSe heterostructures on InAs(001) substrates and studies of their optical and structural properties. The CdMgSe energy gap versus composition dependence is determined. The zinc-blende MgSe band-gap energy and optical bowing parameter are estimated to be 4.05 eV and 0.2 eV, respectively. The CdSe quantum wells embedded into CdMgSe barriers demonstrate intense photoluminescence. Effective mass approximation calculations of electron-heavy hole optical transitions in CdSe quantum well are in a good agreement with the experimental data obtained.

Opis:: The characteristics of ZnSe-based electron beam pumped semiconductor lasers are presented in detail. The laser structures consist of a 0.6 μm thick superlattice waveguide centered with ten equidistantly placed CdSe/ZnSe quantum dot active layers. The maximum light output pulse power of 12 W per facet at room temperature along with an extremely high quantum efficiency of ≈8.5% were obtained at an electron beam pumping energy of 23 keV (the laser wavelength is of 542 nm). The calculations of a spatial distribution of non-equilibrium carrier concentration within the semiconductor structures under electron beam pumping are presented. The possible ways of further improvement of laser efficiency are discussed.
