Abstract
The linear absorption coefficient of InAs/Tn(x)Ga(1-x)Sb superlattices is optimized based on an 8x8 envelope-function approximation (EFA) mo del. The effect of layer widths, indium content, buffer choice, substr ate orientation, interface type, layer growth order, piezoelectricity, and layer width variations on the cutoff wavelength and the linear ab sorption coefficient is investigated. We propose specific superlattice parameters that optimize absorption for superlattices grown on GaSb a t three cutoff wavelengths.
