Abstract
- We demonstrate a deterministic Purcell-enhanced single photon source realized by integrating an atomically thin WSe2layer with a circular Bragg grating cavity. The cavity significantly enhances the photoluminescence from the atomically thin layer and supports single photon generation with g(2)(0) < 0.25. We observe a consistent increase of the spontaneous emission rate for WSe2emitters located in the center of the Bragg grating cavity. These WSe2emitters are self-aligned and deterministically coupled to such a broadband cavity, configuring a new generation of deterministic single photon sources, characterized by their simple and low-cost production and intrinsic scalability.
