    摘要： A waveguide assembly is provided that includes a waveguide region and at least one photonic crystal (PhC) region. The waveguide region includes a longitudinally extending core that has an input channel and at least one output channel, and a cladding at least partially surrounding the core for confining signals within the core. The PhC region(s), in turn, extend laterally through at least a portion of the core to at least partially direct signals propagating through the core. The PhC region(s) can extend through at least a portion of the core to thereby form, for example, a bend, beamsplitter, polarizing beamsplitter, Mach-Zender interferometer or ring resonator for signals propagating through the core.

    摘要： The viewing angle brightness sensitivity typically encountered in tiled rear projection display systems cannot be solely overcome by edge blending and calibration techniques. The rear projection array display-screen system of this invention, being comprised of a micro-structure array screen combined with a conventional diffusion screen, overcomes this viewing angle brightness sensitivity in both linear as well as matrix tiled rear projection display systems including those that use wide field-of-view projectors. The latter capability enables low form-factor and compact packaging of tiled rear projection display systems.

    摘要： A spatio-temporal directional light modulator is introduced. This directional light modulator can be used to create 3D displays, ultra-high resolution 2D displays or 2D/3D switchable displays with extended viewing angle. The spatio-temporal aspects of this novel light modulator allow it to modulate the intensity, color and direction of the light it emits within an wide viewing angle. The inherently fast modulation and wide angular coverage capabilities of this directional light modulator increase the achievable viewing angle, and directional resolution making the 3D images created by the display be more realistic or alternatively the 2D images created by the display having ultra high resolution.
