Abstract :
In this work exciton spin state degeneracy of InAs quantum dots (QDs) have been shown to be lifted by applying a magnetic field. A strong coupling between a QD exciton spin state and a photonic crystal cavity was demonstrated as well as two QDs and the cavity. Applying a magnetic field to the QD-cavity system not only serves as a method for tuning QD emission frequency, but also opens the possibility of exploring the interactions between a cavity and multi-level quantum emitter systems.
