A yellow, gold or amber blinking light on a computer varies in meaning between systems, but in general, these lights are designed to give clues as to the power and activity states of the computer. Not ...

Computing lighting that looks real remains complex and inefficient, as the necessary consideration of all possible paths light can take remains too costly to be performed for every pixel in real-time.

Computers that use light instead of circuits to run calculations may sound like a plot point from a Star Trek episode, but researchers have been working on this novel approach to computing for years.

Computers created within the next two decades could revolve around a technology in which laser beams converge inside crystals the size of sugar cubes, forming holographic images for processing huge ...

A new type of computer that uses light rather than electricity could perform calculations faster, using less energy and less space. Computer chips are made up of millions or billions of logic gates.

An optical, in-computer breakthrough being explored by researchers at University of North Carolina at Chapel Hill will let computers run cooler and faster. Light-carrying, miniature wires are ...
