We report on the formation and optical characteristics of ridge waveguide structures 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 (Ts), and introduction of growth interruptions. Stimulated emission from these ridge QWR laser structures was observed at temperatures 4.7-290 K by optical pumping.
