Abstract :
A high-temperature characteristics of 1.52 μm InGaAs ridge waveguide laser diode (LD) with InGaAs/InAlAs short period superlattices (SPSs) barriers is reported. The SPSs are grown by digital-alloy molecular beam epitaxy (MBE). There have been similar studies at the 0.98 μm LD using GaAs/AlGaAs SPSs barrier (T0=300 K) and 1.3 μm InGaAsP LD using (InGaAsP)4/(InP)5 SPSs barrier (T0=90 K). On the basis of above context, It is reasonable to adapt SPSs to InGaAlAs/InGa(Al)As system. In this letter, a high-temperature characteristics of 1.52 μm InGaAs LD with (InAlAs)0.4(InGaAs)0.6 SPSs barriers grown by digital alloy MBE technique is reported for the first time.
