Device for the multiplication of charge carriers by an avalanche

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.
