Abstract
A quantum-dot cascade laser which eliminates single phonon decays associated with quantum-well devices. The elimination of single phonon decays is realized by a three-dimensional confinement resulting in a several-order-of-magnitude reduction in the threshold current. Dot size, dot density and dot uniformity requirements are presented along with several embodiments.
