Abstract :
Composition grading is a common technique in design of MQW optoelectronic devices to improve optical and electrical confinement. For example graded index separate confinement heterostructure (GRIN-SCH) is commonly used to improve the lasing threshold and efficiency of GaAs/AlGaAs QW laser diodes. In this study, we shall investigate some of the fundamental effects as a result of composition grading of the quantum well using numerical simulation (the LASTIP software of Crosslight Software).
