Abstract

We demonstrate the integration of solid-state single-photon sources in nanophotonic waveguides and show how photons can be collected from several such emitters simultaneously. A lithographic technique here allows us to position solution-based colloidal quantum dots or nanodiamonds hosting defect centers with tens of nanometer accuracy within nanophotonic devices at chip-scale. We further present a novel reinforcement learning-based inverse design approach for realizing photonic integrated circuit components that enable the efficient manipulation of optical modes in devices with minimal footprint. Combining single-photon sources and circuits on a nanophotonic chip will benefit a wide range of applications in quantum technology.
