Tg. Kim et al., DESIGN AND FABRICATION OF A NARROW STRIPE GAAS ALGAAS QUANTUM-WIRE LASER/, Journal of the Korean Physical Society, 30, 1997, pp. 123-126
A high-performance narrow-stripe GaAs/AlGaAs quantum wire (QWR) laser
with a p-n junction current-blocking layer has been designed, simulate
d and fabricated. For the design's aspect, the thicknesses and the dop
ing concentrations of p- and n-current-blocking layers, the conductive
stripe width, the calculated light wavelength of both quantum well an
d quantum wire, etc. were considered. In addition, to see the effect o
f current-confinement into the QWR active region, the physical structu
re of the QWR laser was modeled as a simple electrical circuit. Based
on these simulated results, the QWR laser was fabricated using two-ste
p MOCVD growth with a wet etching technique.
