The results of a laser design that uses dual Si impurity-induced disordering stripes to both bury the active region and provide lateral electron injection are reported. Without heatsinking, lasers have room temperature CW threshold current as low as 2.77 mA and a single facet external quantum efficiency as high as 30%.
