Abstract :
Reliable high-power operation of transverse-mode stabilised InGaAlP laser diodes has been achieved by using a selectively-buried-ridge waveguide structure with a very thin (150 AA) active layer. A strained In0.62Ga0.38P active layer and a 800 mu m cavity length were employed to reduce the operation current density at high-power and high-temperature operation. A highly reliable operation for over 2000 h has been achieved with a 40 mW output at 40 degrees C. The lifetime of the lasers was limited by the operation current density.
