Hold on to your tinfoil hats because there’s certainly a conspiracy theory a-brewin’ here. The Pentagon has confirmed it’s testing lasers that can talk. Huh? Weapons researchers at the U.S. Department of Defense have been working on less deadly means of warfare, including this laser weapon that can send brief messages — in the form
One of the biggest challenges in developing integrated photonic circuits — which use light rather than electrons to transport information — is to control the momentum of light. Colors of light travel at different speeds through a material but in order for light to be converted between colors, it needs to have the same momentum
An array of thousands of constantly moving hexagonal mirrors, each measuring just 1 millimeter square, could one day enable a host of cutting-edge applications, from self-driving cars and laser-based communication and manufacturing to advanced microscopes and telescopes. The Livermore micromirror array delivers an unprecedented combination of capabilities, including tight control of every mirror’s three degrees
