The GaAs-GaAlAs graded-index separate confinement heterostructure was grown selectively by molecular beam epitaxy on a SiO/sub 2/-masked GaAs (100) substrate. The stripe windows on the SiO/sub 2/ mask were 10 ..mu..m in width and were oriented along (011-bar) direction. The laser diodes thus fabricated lased in a single longitudinal mode with a side mode suppression ratio of 95:1. Both the longitudinal mode and the single-lobe far-field pattern were stable up to 4I/sub th/.
