摘要：
A study of Zn diffusion behavior in capped mesa buried heterostructure lasers reveals the Zn profile in the base epitaxial region of InGaAsP/InP heterostructures to be dominated by diffusion during regrowth. This diffusion behavior has enabled us to fabricate a laser without any Zn doping in the p clad during base growth. The lasing characteristics at 25 degrees C are comparable to those of normally Zn-doped structures. The Zn diffusion into the undoped cladding layer, and thus, the temperature performance of these lasers are dependent on the level of Zn doping in third growth.
