Abstract

A new kind of superlattice system is proposed where wells of two different widths are closely associated through thin barriers.The narrow wells are used as the optically active part of the device where the excitonic absorption can be bleached very rapidly by an external light source. The wider wells trap the excess carriers in a very short time so that the absorption is quickly restored. All optical switches with a time response shorter than 1 ps can be made with such a system.
