Midinfrared GaInSb/AlGaInSb quantum well laser diodes grown on GaAs. .

摘要

The realization of midinfrared GaInSb/AlGaInSb type I quantum well diode lasers grown on GaAs is reported. Lasing was observed up to 95 K, at an emission wavelength of ~3.5 µm, threshold current density of 115 A/cm2, and with a characteristic temperature T0~51 K.
