Abstract: A method for producing a single photon source includes functionalizing a top surface of a plasmonic thin film to form a functionalized thin film, depositing a polymer on top of the functionalized thin film, lithographically patterning the polymer to form patterned functionalized sites, and targeting nanodiamond particles to the patterned functionalized sites.

Abstract: A method of providing super-resolved images of a photon emitting particle is disclosed, which includes providing a machine-learning (ML) platform, wherein the ML platform is configured to receive pixel-based sparse autocorrelation data and generate a predicted super-resolved image of a photon emitting particle, receiving photons from the photon emitting particle by two or more photon detectors, each generating an electrical pulse associated with receiving an incident photon thereon, generating sparse autocorrelation data from the two or more photon detectors for each pixel within an image area, and inputting the pixel-based sparse autocorrelation data to the ML platform, thereby generating a predicted super-resolved image of the imaging area, wherein the resolution of the super-resolved image is improved by √n as compared to a classical optical microscope limited by Abbe diffraction limit.

Abstract: An ultra-thin planar device is used for arbitrary waveform formation on a micrometer scale, regardless of the incident light's polarization. Patterned perforations are made in a 30 nm-thick metal film, creating discrete phase shifts and forming a desired wavefront of cross-polarized, scattered light. The signal-to-noise ratio of these devices is at least one order of magnitude higher than current metallic nano-antenna designs. The focal length of a lens built on such principle can also be adjusted by changing the wavelength of the incident light. All proposed embodiments can be embedded, for example, on a chip or at the end of an optical fiber.

Abstract: A planar optical device, comprised of sets of nanometer-scale holes milled into a thin metal or ceramic film of subwavelength thickness serves to form arbitrary waveform of light. The holes form a pattern, preferrably rings, of various sizes in order to achieve a given phase front of light due to photonic effect. When designed as a lens, the device focuses incident light into a tight focal spot. In symmetric design, the focusing property of the device does not depend on the incident polarization angle. The lens can be manufactured based on high-throughput fabrication methods and easily integrated with a chip or placed at the end of an optical fiber.

Abstract: A particle sensing system which includes a plurality of micro-lenses which focus light from an unfocused or loosely focused light source onto a corresponding plurality of focus regions on a surface containing plasmonic structures. The absorption of light by the plasmonic structures in the focus regions results in heat dissipation in the plasmonic structures and consequently increases surface temperature in the focus regions. When an electrical field is applied to a sample fluid in contact with the surface, multiple electrothermal flows are induced in the fluid which rapidly transport suspended particles to the focus regions on the surface. The particles can then be captured and/or sensed.
