Performance enhancement of AlGaN deep-ultraviolet laser diode using compositional Al-grading of Si-doped layers

•Compositional grading of AlGaN layers is used to increase the optical confinement factor (OCF), and gain of DUV LD.•Compositional grading of waveguides (WGs), electron blocking layer (EBL), and cladding layers (CLs) demonstrated that the device characteristic can be improved.•Along with WGs and EBL...
