  • Abstract
    Semicylindrical Zn-diffused stripe (SCD) GaAlAs lasers with a very narrow current-confining stripe and sufficient refractive-index step along the active layer are described. They have the lowest threshold current among this type of device previously reported. The devices having a 200 ¿m cavity length showed a CW threshold current of only 22 mA at 25°C and 45 mA at 105°C. Sufficient current confinement made it possible to operate at temperatures up to 165°C.
