Integrated plasmonic nanocircuits are highly promising building blocks for future quantum optical applications. In combination with self-assembled quantum dots as stable, bright and narrow-band single-photon sources, ultra-compact nanocircuits operating below the diffraction limit can be designed. A crucial aspect is the coupling of the quantum dot emission into plasmonic waveguide modes. In this work, we propose a plasmon--quantum dot hybrid structure which offers a highly efficient coupling scheme due to enhanced light-matter-interaction. We perform numerical simulations to optimize the coupling efficiency and show first experimental steps towards fabricating the proposed structure.
