   Abstract:
   In this paper, we present a QDIP heterostructure, comprised of InAs QDs embedded in a periodic AlAs/GaAs superlattice (SL) barrier. This SL barrier allows us to control the performance of QDIPs, culminating in state-of-the-art responsivity and conversion efficiency for a QDIP with a total SL period of 15 nm
