Abstract :
High-power, double quantum well, separate confinement GaAs/AlGaAs diode lasers are characterised by power against current and spectral measurements. Short cavity length devices exhibit lower threshold current densities than equivalent single-quantum-well devices. Unlike single-quantum-well devices, no n=2 transitions are observed even for devices as short as 150 μm at 80°C. These devices are more suitable for monolithic surface-emitting applications
