Photoluminescence and Lasing Characteristics of GaInNAs/GaAsP Strain-Compensated Quantum Wells

摘要

We report on the photoluminescence (PL) and lasing characteristics of GaInNAs/GaAsP strain-compensated quantum wells (QWs) as a function of the amount of strain-compensation. The PL intensity of GaInNAs/GaAs(P) QWs was increased by increasing both the thickness and phosphorous (P) content of GaAsP strain-compensation layers. It was also shown that strain compensation is beneficial for increasing of the number of GaInNAs QWs. The threshold current densities of lasers were improved by introducing strain compensation.
