摘要
One of the main obstacles to coupling two quantum dots (QDs) to a single nanocavity mode in a cavity quantum electrodynamics system is the ability to independently tune the QD frequencies. We demonstrate that in a GaAs photonic crystal membrane structure with two embedded QD layers, the QD emission frequencies of one QD layer can be tuned independently of the other by applying a voltage across only one of the QD layers.
