Abstract
Long wavelength InGaAsN/GaAs single quantum well (SQW) laser diodes have been grown by solid source molecular beam epitaxy (MBE) using Sb as a surfactant. A record low threshold current density of 1.47 kA/cm/sup 2/ and a quantum efficiency of 0.11 W/A are reported for broad area laser diodes (LDs) operating at a wavelength of 1.275 /spl mu/m under pulsed operation at room temperature.
