WebNew InAlGaAs/AlGaAs SL structures with thin (close to 2 nm) quantum well layers and the highest possible (up to 35 %) concentrations of In within the QW layers were and quantum efficiency spectra obtained at lowered activation are presented at Figure 1, revealed a rather wide plateau in the vicinity of the maximum polarization WebThe second part of this thesis focuses on the three types of quantum well (QW) lasers; phosphor-free1.3µm InAlGaAs strain-compensated multiple-quantum-well (SCMQW) lasers on InP (100), InGaAsNSb/GaAs quantum wells (QWs) grown on GaAs (411)A substrates and mid-infrared InGaAsSb lasers with digitally grown tensile-strained AlGaAsSb barriers.
WebThe PL peak wavelength is ~1.53 µm. The PL intensity of InAlGaAs MQWs increases with the growth temperature (as indicated by the reactor thermocouple), a tendency similar to that of other Al−containing materials. Fig.2.
