Abstract :
The authors have fabricated a ZnCdSe/ZnSSe/ZnMgSSe separated confinement heterostructure (SCH) laser diode (LD) with a 3 nm ZnTe:N contact layer/ZnSe:N/ZnTe:N superlattice layer (SL)/ZnSe:N cap layer with optimised [N] and a ZnCdSe active layer with VI-rich growth conditions and optimised stripe width. The LD achieved over 300 h LD operation at a constant output power of 1 mW at low voltage (4 V)
