We have grown InGaAs-InGaAlAs-InP strained quantum well lasers with wavelength up to 2.2 μm in solid-source molecular-beam epitaxy. A continuous-wave threshold current density of 370 A/cm2 at room temperature has been achieved for 2.2 μm lasers. Continuous-wave operation at temperature as high as 100°C has been demonstrated and a characteristic temperature of 72 K has been achieved for 1.79 μm lasers.
