Wg. Pan et al., A HIGHLY LUMINESCENT CRESCENT-SHAPED TENSILE-STRAINED GAASP ALGAAS QUANTUM-WIRE LASER STRUCTURE/, Journal of crystal growth, 170(1-4), 1997, pp. 585-589
We report a highly luminescent crescent-shaped tensile-strained GaAsP/
AlGaAs quantum wire (QWR) laser structure on 3 mu m periodic V-grooves
grown by low-pressure (100 Torr) metalorganic vapor phase epitaxy (MO
VPE). Photoluminescence studies show that carriers are efficiently cap
tured from neighboring quantum well layers (QWLs) into QWRs, which giv
e efficient luminescence. The QWR light emitting diode (LED) shows pol
arization insensitivity resulting from the tensile strain properties o
f the QWR structure.
