Abstract

The nitrogen vacancy is a photostable emitter in diamond which is optically accessible at room temperature and a potential candidate for quantum information processing as a spin register. The challenge facing research today is the efficient collection and manipulation of the NV’s emissions, such as enhancing the zero phonon line transitions for a coherent spin-photon interface. This project focuses on integrating ultra-thin diamond membranes with established photonic devices. By bonding the diamond to GaN, for example, mode simulations show that light can be coupled significantly into and out of the defect allowing processing across large area PICs.
