Abstract
InGaAs-InAlGaAs quantum well (QW) structures offer an alternative material system for the fabrication of long-wavelength optoelectronic devices (λ = 1.55 μm) and possess a number of advantages over the more commonly used InGaAsP system including a larger conduction-band offset ratio (ΔEc/Eg),1 simplified growth technology, and significantly greater thermal stability.
