Abstract
GaInAs/AlGaInAs/InP separate-confinement heterostructure multiquantum well (SCH-MQW) laser diodes emitting at 1.55 mu m have been fabricated by atmospheric-pressure MOCVD. Room-temperature pulsed threshold current densities were 940 A cm-2 and 830 A cm-2 for 500 mu m and 800 mu m-long cavities, respectively. These are the lowest values reported to date for long wavelength MQW laser operation.
