Abstract

A quantum cascade emitter structure is suggested that is based on electronic transitions in an artificial bandstructure of coupled quantum wires in contrast to the conventional quantum layer systems. The electron transport is normal to the wires in a GaAs/ AlGaAs heterostructure produced by the cleaved-edge overgrowth method. For a realistic system of this type, the relevant rates of radiative ...
