High Reflection

MBE growth of GaSb / InGaAsSb / GaSb heterostructures of high crystal quality is performed under continual RHEED control. Transmission spectra of the films forming multiple quantum wells in λ ≈ 2–3 μm region confirm possibility to control optical properties of the structures through quantum confinement and through the content of semiconductor elements. New design of saturable absorption semiconductor mirror (SESAM) for Cr 2+: ZnSe laser is proposed and manufactured on the base of the single quantum well GaSb / InGaAsSb / GaSb placed between dielectric antireflection and broadband high reflection coatings.

We present an efficient method to calculate the quantum-confinement energy of charge carriers in the ( ZnSe )M( CdSe )N (001) multiple quantum wells (MQW). The method is based on the 3D empirical sp3s* tight-binding models, which include the spin-orbit coupling. The method can handle large systems while it takes account of the band mixing caused by the strain and confinement. In these perspectives, it proves itself more reliable than the traditional effective-mass approach (EMA) by further generating more relevant information about the quantum states localized within the wells; in particular, the number of bound states and their energy levels and their corresponding wavefunctions were obtained based on more realistic physical models. The quantum-confinement energy, bandgap energy, and band structures are studied versus the CdSe well width (N). The results are found to be comparable with those experimentally obtained using photoluminescence.
