We have grown InGaAs-InGaAlAs-InP strained quantum well lasers with wavelen
gth up to 2.2 mum in solid-source molecular-beam epitaxy. A continuous-wale
threshold current density of 370 A/cm(2) at room temperature has been achi
eved for 2.2 mum lasers. Continuous-wave operation at temperature as high a
s 100 degreesC has been demonstrated and a characteristic temperature of 72
K has been achieved for 1.79 mum lasers. (C) 2001 Elsevier Science B.V. Al
