Abstract
AlGaAs graded-index separate-confinement heterostructure lasers with l
ateral mode confinement are realized by one time metalorganic chemical
vapor deposition with silicon dioxide stripes as selective masks and
current blocking layers. The effect of the active region width on lasi
ng characteristics is investigated. The threshold current and external
quantum efficiency are around 12 mA and 70%, respectively, for narrow
lasers. Elevated waveguide structure formed by the growth-rate differ
ence between (100) and sidewall planes was effective for stable latera
l mode characteristics.
