  • Abstract
    We present a new structure of AlGaAs/GaAs DH lasers consisting of two oppositely facing terraced-substrate cavities in series. Polarisation change at the junction results in internal reflection and produces a mode-selection effect. A stable single longitudinal mode is observed over a wide current range from 100 to 150 mA. The dominant lasing mode is locked over a 7° temperature variation. The lowest observed threshold current is 50 mA.
