Abstract
Extremely low threshold current density operation of the LPE grown 670 nm GaInAsP/AlGaAs lasers has been realised with drastic improvement of the characteristic temperature of the threshold from 45 K to 90 K by increasing the Al content of the AlGaAs cladding layers from 0.7 to 0.95. The threshold current density was 1.7 kA/cm2, about one-third of the previously reported value of 5-6 kA/cm2.
