We present state-of-the-art performance of 1.3 μm GaInNAs lasers on GaAs grown by molecular beam epitaxy. The lowest achieved threshold current density is 297, 150 and 133 A/cm2 per quantum well (QW) for single, double and triple QW broad area lasers with a cavity length of 1 mm. The characteristic temperature is 93-133 K in the ambient temperature range of 10-80 °C for broad area lasers depending on the cavity length, and increases to 163-208 K for ridge waveguide lasers as a result of temperature insensitive lateral carrier diffusion in QWs. The maximum 3 dB bandwidth of 17 GHz is achieved in a double QW laser. Uncooled 10 Gb/s operation up to 110 °C has been demonstrated.
