Abstract

Single lateral InGaAs quantum dot molecules are embedded in a planar microcavity in order to enhance the luminescence extraction efficiency and a combination of metal-organic vapor phase and molecular beam epitaxy samples are produced that has displayed an enhanced single-photon emission rate. The presence of a polarization fine structure splitting of the molecular neutral excitonic states has led to two polarization split classically correlated biexciton-exciton cascades.
