The authors report the first implanted-planar-buried-heterostructure, graded-index, separate-confinement-heterostructure (IPBH-GRINSCH) laser in (AlGa)As/GaAs. Ion implantation is used to form p-n-p-n current blocking layers and to create a buried-heterostructure waveguide. This results in significantly reduced fabrication complexity of high-quality, index-guided laser diodes compared to regrowth techniques, and in contrast to diffusion-induced disordering, allows for the creation of self-aligned, buried, blocking junctions. The authors demonstrate kink-free, CW operation of single-stripe IPBH-GRINSCH lasers along with single-lobed near- and far-field optical emission patterns, consistent with index-guided operation.
