Abstract
The authors report the first successful demonstration of self-organied InGaAs quantum wire (QWR) laser diodes (LDs) utilising GaAs multi-ato mic steps at 77K by pulsed current injections. The lasing wavelength o f InGaAs QWR-LDs is consistent with the peak position of photoluminesc ence spectra at 77K. When a cavity direction is perpendicular to the Q WR's array direction, the threshold current density of InGaAs QWR-LDs is smaller than that of quantum well LDs.
