Helicity multiplexed broadband metasurface holograms
Metasurfaces are engineered interfaces that contain a thin layer of plasmonic or dielectric nanostructures capable of manipulating light in a desirable manner. Advances in metasurfaces have led to various practical applications ranging from lensing to holography. Metasurface holograms that can be switched by the polarization state of incident light have been demonstrated for achieving polarizat...
متن کاملMetasurface holograms for visible light
Holography, a revolutionary 3D imaging technique, has been developed for storing and recovering the amplitude and phase of light scattered by objects. Later, single-beam computer-generated phase holography was proposed for restoring the wavefront from a given incidence. However, because the phase modulation depends on the light propagation inside the material, the thickness of phase holograms u...
متن کاملBroadband metasurface holograms: toward complete phase and amplitude engineering
As a revolutionary three-dimensional imaging technique, holography has attracted wide attention for its ability to photographically record a light field. However, traditional phase-only or amplitude-only modulation holograms have limited image quality and resolution to reappear both amplitude and phase information required of the objects. Recent advances in metasurfaces have shown tremendous op...
متن کاملMicro-optical elements fabricated by metal-transparent-metallic-oxides grayscale photomasks.
One-step gray-tone lithography is the most effective approach to making three-dimensional (3D) micro-optical elements (MOEs). Metal-transparent-metallic-oxide (MTMO) grayscale masks are novel and quite cost effective. In this paper, through the successful fabrication of 3D SiO(2) MOEs by gray-tone lithography and reactive ion etching, we thoroughly investigate the practical technique needs of M...
متن کاملMetasurface-Mediated Quantum Entanglement
Entanglement-based quantum science exploits subtle properties of quantum mechanics into applications such as quantum computing, sensing, and metrology. The emerging route for quantum computing applications, which calls for ultracompact, integrated, and scalable architecture, aims at onchip entangled qubits. In this context, quantum entanglement among atomic qubits was achieved via cold-controll...
