Abstract

Very low threshold current density InGaAs/GaAs quantum well laser diodes grown by molecular beam epitaxy on InGaAs metamorphic buffers are reported. The lasing wavelength of the ridge waveguide laser diode with cavity length of 1200m is centred at 1337.2nm; the threshold current density is 205A/cm2 at room temperature under continuous-wave operation.
