Abstract

Here we report on our recent experimental efforts towards the design, fabrication and characterization of various metasurface structures that would allow spatial and temporal control of photon emission from atomic ensembles, as well as state preparation of solid state and atomic quantum emitters. The emphasis is placed on the development of two distinct categories of structures: (i) Micro- and meso-scale free-space self-polarizing confocal cavities formed by dielectric metasurfaces. (ii) flat hyper-gratings fabricated on the surface of a diamond, which would make the radiation pattern from NV centers in the diamond to be highly directional so that the emitted photons can be collected with high efficiency.
