Abstract

We demonstrate resonant excitation of a semiconductor quantum dot embedded in a p-i-n diode structure in and out of a photonic crystal cavity. We investigate the modification of the spontaneous emission rate and the photon collection efficiency of quantum dots due to the presence of a photonic bandgap. The resonant excitation together with deterministic charging of the quantum dot embedded in a photonic crystal, can be used for single electron spin measurement.
