Examines the effect of excess zinc (Zn) around the active-stripe mesa on the lasing threshold current of a [011] oriented InGaAs/InP buried-heterostructure. Confirmation of the poor device performance; Factor affecting the localized enhancement of the Zn level in the first p-InP layer; Diffusion of excess Zn across the sidewall interfaces.
