Abstract :
AlGaAs/GaAs distributed feedback (DFB) lasers with a ridge waveguide structure emitting at 0.88 ¿m were fabricated by normal-pressure metalorganic chemical vapour deposition (MOCVD). The DFB lasers have a low threshold current around 55 mA at room temperature and can be operated stably in a single longitudinal mode up to 40°C.
