Abstract

Current developments in semiconductor nanolasers utilize effects of cavity quantum electrodynamics. Optical resonators with highly efficient three-dimensional mode confinement are combined with quantum dot (QD) emitters in which the three-dimensional carrier confinement leads to an atom-like carrier density of states. For devices with a small number of 50-200 QD emitters and large spontaneous emission coupling factors laser emission with strongly reduced laser threshold has been demonstrated [1].
