They have now demonstrated a programmable, wireless device that can control light, such as by focusing a beam in a specific direction or manipulating the light\u2019s intensity, and do it orders of magnitude more quickly than commercial devices.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In a scene from \u201cStar Wars: Episode IV\u2014A New Hope,\u201d R2D2 projects a three-dimensional hologram of Princess Leia making a desperate plea for help.
