Abstract: Solid-state single-photon emitters have advantages of the outstanding optical properties of atoms and the convenience and extensibility of solid-state systems. So they play an important role in scalable optical quantum information technology. However, single photons emitted from solid-state single-photon sources in vacuum have some drawbacks, such as low spontaneous radiation rates, omnidirection, and random polarization states. These drawbacks greatly limit their applications. Surface plasmons supported by metallic micro-nano structures have huge field enhancement and sub-wavelength field confinement. Therefore, a variety of metallic micro-nano structures have been designed to manipulate single-photon emission. Here, recent advances in exploiting metallic micro-nano structures for enhancing emission and tailing emission direction and polarization are reviewed. Their performances are compared and the control mechanisms are analyzed. Finally, the challenges and developments of the manipulation of single-photon emission by metallic micro-nano structures are prospected.

Key words: nanophotonics, single-photon emitters, metallic micro-nano structures, emission enhancement, emission direction, emission polarization
