Efficient and bright integrated solid-state single photon sources, preferably with narrow-bandwidth emission are a crucial prerequisite for future applications in quantum information science.
We report on our approach towards an integrated microresonator-enhanced single-photon source, consisting of nano-sized quantum emitters evanescently coupled to resonant photonic structures. In our proposed system we make use of single quantum emitters coupled deterministically [1] to a monolithic add-drop ring microresonator configuration. This hybrid system locally enhances the intensity of the excitation light and allows easy separation of the resonant excitation light from the emitted single photons via the two well-defined polarisations of the guided modes. Resonant excitation of the quantum emitters at the zero-phonon line promises a strong suppression of spectral diffusion and therefore a narrow spectral emission [2].
The proposed system has a narrow-bandwidth emission of single photons coupled to a single optical mode and is promising as a source e.g. in quantum information and quantum cryptography.
