Tiny gears on computer chips generate a vortex of light that could boost optical computing For the first time, researchers have used tiny gears made of germanium to generate a vortex of twis... Read more
New nanoscale light switch is a step toward light-based computers Researchers from the University of North Carolina at Chapel Hill have reached a new milestone on the way to optical computin... Read more
Technique would allow addition of optical communication components to existing chips with little modification of their designs. Two and a half years ago, a team of researchers led by groups... Read more
By forcing light to go through a smaller gap than ever before, researchers have paved the way for computers based on light instead of electronics. Light is desirable for use in computing bec... Read more
A research team at Swinburne University of Technology has overcome a fundamental law of optical science that could lead to faster and more energy-efficient optical computing. It would allow... Read more
