Wet thermal oxidation of a strained balanced superlattice structure, epitax
ially grown on InP and including high Al content layers, is investigated. T
he oxidation kinetics are studied as a function of temperature and oxidatio
n duration. The results are interpreted with a simple diffusion model. We p
ropose use of this structure as a confining layer for monolithic long wavel
ength vertical cavity surface emitting lasers. (C) 1999 American Institute
