Abstract
An avalanche photodetector of the heterojunction type comprises an intermediate region between two end regions made from distinct semiconductor materials. The intermediate region comprises a lattice of slices of varying thicknesses of alternating layers of the material of the end regions thus forming a system of coupled quantum wells whose thicknesses and whose number of slices are determined so that the response time of the photodetector is less than a maximum given time, while maintaining the number of coupled quantum wells to a minimum.
