H. Gebretsadik et al., LATERAL OXIDATION OF INALAS IN INP-BASED HETEROSTRUCTURES FOR LONG-WAVELENGTH VERTICAL-CAVITY SURFACE-EMITTING LASER APPLICATIONS, Applied physics letters, 72(2), 1998, pp. 135-137
We have studied the wet thermal oxidation of In0.52Al0.48As and its po
tential application in current and optical confinement in vertical cav
ity surface emitting lasers (VCSELs). Two types of InP-based heterostr
uctures were used to study the effect of adjacent layer compositions o
n the lateral oxidation behavior of the InAlAs. It was found that the
oxidation of I0.52Al0.48As with InP adjacent layers, compared with In0
.53Ga0.47As adjacent layers, proceeded faster, more uniformly and with
minimal degradation of the surrounding layers making it ideal for opt
oelectronic applications. (C) 1998 American Institute of Physics.
