Abstract

The carrier dynamics of different types of long wavelength QDs will be discussed, along with experimental results on high efficiency QD light emitters. Recent experiments show that for low temperature operation, QD microcavity light sources can obtain efficiencies exceeding 16% for very low bias currents
