Abstract

Reduction of the dimensionality of electron motion by using quantum wells, quantum wires, and quantum dots brings new phenomena to semiconductor physics and introduces new device concepts.^1,2 Moreover, recent intensive investigations of the concept of controlling photon-electron interaction by using microcavities in semiconductor lasers have led to, for example, zero-threshold semiconductor lasers. As a consequence of these investigations, we find that the full quantization of electrons and photons by using three-dimensional microcavity and quantum dots is one of the ultimate structures in future semiconductor lasers.
