Abstract: A transparent display includes nanoparticles having wavelength-selective scattering (e.g., resonant scattering) to preferentially scatter light at one or more discrete wavelengths so as to create images. The nanoparticles transmit light at other wavelengths to maintain a high transparency of the display. The nanoparticles are disposed in proximity to a thin film, which can enhance the scattering the process by reflecting light back to the nanoparticles for re-scattering or increasing the quality factor of the resonant scattering.

Abstract: An integrated optical beam steering device includes a planar dielectric lens that collimates beams from different inputs in different directions within the lens plane. It also includes an output coupler, such as a grating or photonic crystal, that guides the collimated beams in different directions out of the lens plane. A switch matrix controls which input port is illuminated and hence the in-plane propagation direction of the collimated beam. And a tunable light source changes the wavelength to control the angle at which the collimated beam leaves the plane of the substrate. The device is very efficient, in part because the input port (and thus in-plane propagation direction) can be changed by actuating only log2 N of the N switches in the switch matrix. It can also be much simpler, smaller, and cheaper because it needs fewer control lines than a conventional optical phased array with the same resolution.

Abstract: Methods and systems are disclosed that enhance the yield and speed of emission and control the spectral and angular emission of light emitted by materials under irradiation by high-energy particles through a process known as scintillation. In each case, a photonic structure (of nano- or micron-scale feature sizes) is integrated with a scintillating material, and the photonic structure enhances the yield or controls the spectrum of the material. Various embodiments of this technology and practical demonstrations are disclosed.
