We report on the formation and optical characteristics of ridge waveguide s
tructures containing quantum wires (QWRs). To form a waveguide? we adopted
digital alloys, i.e. short-period superlattices (SLs), rapid changes of As
fluxes using valved cells, growth temperatures (T-s), and introduction of g
rowth interruptions. Stimulated emission from these ridge QWR laser structu
res was observed at temperatures 4.7-290 K by optical pumping. (C) 1999 Els
