Abstract :
The diffusion behaviour of Zn during MOCVD of InGaAsP/InP capped mesa buried heterostructure lasers has been reported to exhibit a threshold concentration for significant diffusion, which can result in Zn in the active region. The authors report on the electro-optical characteristics of these lasers and show the effect of Zn in the active region on the threshold current and differential quantum efficiency
