Abstract :
High performance InGaAs/InGaAsP/InP quantum dot lasers have been demonstrated. The cw operation up to 75degC has been achieved with the maximum external quantum efficiency of 44%, the output power of 160 mW. However, several peculiar behaviors have been observed caused by the inhomogeneity of the gain spectrum.
