The well number of 1.3 mu m GaInAsP/InP strained-layer GRINSCH quantum well lasers has been experimentally investigated in terms of the temperature dependence of the threshold current. A very high CW operating temperature of 170 degrees C with a threshold current of 46.2 mA was obtained for an HR coated laser with eight wells.
