    • Various embodiments of the present invention are directed to negative refractive index-based holograms that can be electronically controlled and dynamically reconfigured to generate one or more color three-dimensional holographic images. In one aspect, a hologram comprises a phase-control layer having a plurality of phase modulation elements. The phase-modulation elements are configured with a negative effective refractive index and selectively transmit wavelengths associated with one of three primary color wavelength. The hologram also includes an intensity-control layer including a plurality of intensity-control elements. One or more color three-dimensional images can be produced by electronically addressing the phase-modulation elements and intensity-control elements in order to phase shift and control the intensity of light transmitted through the hologram. A method for generating a color holographic image using the hologram is also provided, as is a system for generating a color holographic image.
    • 本发明的各种实施例涉及基于负折射率的全息图,其可以被电子控制和动态地重新配置以产生一个或多个彩色三维全息图像。 一方面,全息图包括具有多个相位调制元件的相位控制层。 相位调制元件被配置为具有负的有效折射率并选择性地传输与三原色波长之一相关联的波长。 全息图还包括包括多个强度控制元件的强度控制层。 可以通过电子寻址相位调制元件和强度控制元件来产生一个或多个彩色三维图像,以便相移和控制透射通过全息图的光的强度。 还提供了使用全息图产生彩色全息图像的方法,以及用于产生彩色全息图像的系统。

    • Various embodiments of the present invention are directed to dynamically and electronically reconfigurable optical devices that can be operated as a lens or prism for incident beams of electromagnetic radiation. The optical devices include a phase-modulation layer (1501) disposed between first and second nanowire layers (1502,1503). Overlapping nanowires can be electronically addressed to implement a selected effective refractive index pattern of one or more regions (1510) of the phase-modulation layer, such that each region refracts a portion of an incident beam of electromagnetic radiation having a wavelength of interest in order to focus, diverge, or bend the incident beam.
