Abstract
Evidence of the type-II alignment at the heterointerface between GaAsSb and InGaAs was obtained with the optimal layer configuration being the asymmetric GaAsSb/InGaAs bilayer. The suitability of GaAs/GaAsSb/GaAs and the strain-compensated GaAsP/GaAs/GaAsSb/GaAs/GaAsP coupled-quantum-well system for long-wave applications was shown. Inhomogeneous linewidth broadening due to lateral composition and thickness modulation was dramatically reduced by the addition of GaAsP strain-compensation layers to GaAsSb-based trilayer quantum-well systems.
