摘要
InAsP/InAlGaAs strained multiquantum-well (MQW) 1.3 mu m lasers with a large conduction band discontinuity are proposed and demonstrated for the first time. An InAsP/InAlGaAs MQW layer with high structural and optical quality was obtained by gas-source molecular beam epitaxy growth combined with postgrowth 650 degrees C rapid thermal annealing. The lasers exhibited a low threshold current density of 1.1kA/cm(2) with an excellent characteristic temperature as high as 116K.
