Scattering holography designed metasurfaces for channeling single-photon emission
arXiv preprint arXiv:2303.02979, 2023•arxiv.org
Channelling single-photon emission in multiple well-defined directions and simultaneously
controlling its polarization characteristics is highly desirable for numerous quantum
technology applications. We show that this can be achieved by using quantum emitters
(QEs) nonradiatively coupled to surface plasmon polaritons (SPPs), which are scattered into
outgoing free-propagating waves by appropriately designed metasurfaces. The QE-coupled
metasurface design is based on the scattering holography approach with radially diverging …

Channelling single-photon emission in multiple well-defined directions and simultaneously controlling its polarization characteristics is highly desirable for numerous quantum technology applications. We show that this can be achieved by using quantum emitters (QEs) nonradiatively coupled to surface plasmon polaritons (SPPs), which are scattered into outgoing free-propagating waves by appropriately designed metasurfaces. The QE-coupled metasurface design is based on the scattering holography approach with radially diverging SPPs as reference waves. Using holographic metasurfaces fabricated around nanodiamonds with single Ge vacancy centers, we experimentally demonstrate on-chip integrated efficient generation of two well-collimated single-photon beams propagating along different 15-degree off-normal directions with orthogonal linear polarizations.
