Abstract :
The letter reports short wavelength emission (7205 Å) from MBE AlGaAs GRINSCH single quantum well lasers. Visible emission is obtained with a 60 Å AlGaAs well containing ≃18% aluminium and both design optimisation and growth conditions lead to low-threshold operation. Broad area Fabry-Perot diodes have threshold current densities as low as 390 A/cm2 and 670 A/cm2 for cavity lengths of 500 μm and 250 μm, respectively
