Abstract :
Visible lasers with two strained GaInP quantum wells and AlGaAs cladding layers have been fabricated using metalorganic vapor phase epitaxy. A dry-etched surface ridge has been chosen as a device structure, which results in a small astigmatism and a low threshold current. Owing to an electroplated heat spreader on top of the ridge, the devices can be operated continuous-wave (CW) junction-side-up at temperatures up to 100°C. Lasers mounted junction-side-down with coated mirror facets operating at 30 mW output power show single-mode behavior and good reliability, as proven by a lifetime test of over 3000 h
