0.67 µm Room-Temperature Operation of GaInAsP/AlGaAs Lasers on GaAs Prepared by LPE

Abstract
Room temperature pulsed operation of 0.67 µm wavelength GaInAsP/AlGaAs lasers on GaAs was achieved, where the lattice constant of GaInAsP active layer neraly matched those of the Al0.6Ga0.4As cladding layers. The threshold current density Jth of the device was 8 kA/cm2.
