Simulation and comparision of GaAs, AlGaAs and GaInP barriers in InGaAs quantum well lasers
View through CrossRef
Abstract
InGaAs quantum wells with GaAs, AlGaAs and GaInP barriers have been simulated, respectively. The InGaAs/GaInP structure reveals a high material gain which could be nearly 1.4 times of that of InGaAs/GaAs. Threshold current of InGaAs/GaInP structure is less than half of InGaAs/AlGaAs. A high slope efficiency of 1.57 W/A from InGaAs/GaInP structure is observed with indium content as high as 0.35. InGaAs/GaInP structure will be the most appropriate candidate to fabricate a laser diode with high slope efficiency and low threshold current.
