Abstract :
A new-structure multiple-quantum-well laser utilising superlattice waveguides and superlattice barriers is proposed and fabricated by molecular-beam epitaxy using GaAs/AlGaAs. Room-temperature CW operation with a threshold current of 40 mA and external differential quantum efficiency per facet of 20% is demonstrated.
