Abstract
Intersubband optical properties of InGaAs/AlAs quantum heterostructures gro wn on InP are analysed. Our calculations based on a recently developed empi rical tight-binding model show that the system is ideally suited for the ta iloring of optical properties in a wide range. In particular, structures ma tching the frequency requirements of ultra-fast fibre optics communications are presented and discussed. (C) 1999 Academic Press.
