1.3-mu m InGaAsN: Sb-GaAs single-quantum-well laser diodes have been grown
by solid source molecular beam epitaxy (MBE) using Sb as a surfactant. A re
cord low threshold of 1.02 kA/cm(2) and a slope efficiency of 0.12 W/A are
obtained for broad-area laser diodes under pulsed operation at room tempera
ture. A characteristic temperature of 64 K and a lasing wavelength temperat
ure dependence of 0.38 mm/degrees C are reported.
