金属微纳结构操控单光子发射体辐射OA北大核心CSTPCD

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.
