Abstract :
Long wavelength bulk InGaAsN semiconductor laser structures have been grown on GaAs substrate by AP-MOVPE, using DMHY and TBAs. After thermal annealing, GaAs/InGaAsN, and AlGaAs/InGaAsN Fabry-Perot laser diodes were processed from the wafers. At room temperature, stimulated emission was observed at peak wavelength from 1.15 to 1.38 /spl mu/m, and laser operation was achieved at 1.16 and 1.275 /spl mu/m. Infinite current density is extrapolated to 12 kA/cm/sup 2/ for AlGaAs/InGaAsN bulk laser diodes.
