The proposed research will design, fabricate, and test nanophotonic structures based on photonic crystals and optical metasurfaces, use these structures to build and demonstrate systems that allow engineering and enhancement of light-matter interactions, and experimentally explore applications of these structures for quantum technologies, such as new types of lasers and non-classical light sources, low-loss interfaces between different quantum information processing platforms, and quantum sensing. The research will explore the following directions: 1) Polarization- and wavelength-dichroic Fabry-Perot optical resonators (cavities) based on photonic-crystal slabs integrated with hollow-core optical waveguides loaded with room-temperature and laser-cooled atomic ensembles 2) Free-space polarization- and wavelength-dichroic Fabry-Perot optical resonators based on optical metasurfaces 3) Optical metasurfaces for directional control of photon emission from individual solid-state and atomic quantum emitters Activities covered in the proposed research directions will include design (based on `conventional' and inverse design techniques) and nanofabrication of these dichroic and chiral photonic-crystal and metasurface structures; assembly and testing of optical resonators based on photonic-crystal and metasurface structures; injection of room temperature gases and loading of laser-cooled atoms into these resonators; coupling solid-state emitters such as quantum dots and diamond defects to these resonators and emission-directing structures; development and demonstrations of novel quantum optics schemes that utilize the unique properties of these photonic structures for applications such as single-photon wavelength conversion, photon detection, quantum memories, quantum sensing, as well as for non-classical light generation and non-conventional lasing; and studies of applications of the above-described platforms with a push toward proof-of-principle demonstrations of practical devices.
