X. Yang et al., Low threshold InGaAsN/GaAs single quantum well lasers grown by molecular beam epitaxy using Sb surfactant, ELECTR LETT, 35(13), 1999, pp. 1082-1083
Long wavelength InGaAsN/GaAs single quantum well (SQW) laser diodes have be
en grown by solid source molecular beam epitaxy (MBE) using Sb as a surfact
ant. A record low threshold current density of 1.47kA/cm(2) and a quantum e
fficiency of 0.11W/A are reported for broad area laser diodes (LDs) operati
ng at a wavelength of 1.275 mu m under pulsed operation at room temperature
