Solid-state single-photon emitters have advantages of the outstanding optical properties of atoms (such as high reliability and high efficiency) and the convenience and extensibility of solid-state systems. Therefore, 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 rate, omnidirectional emission, and random polarization state of emission light, which greatly limit their applications. Surface plasmon polaritons supported by metallic micro-nano structures have huge field enhancement and sub-wavelength field confinement effects. 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 tailoring single-photon emission (including emission enhancement, emission direction, and emission polarization) are reviewed. The performances of different manipulations of single-photon emission are compared and the corresponding control mechanisms are analyzed. Finally, the challenges and developments of the manipulation of single-photon emission from metallic micro-nano structures are prospected.
