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.

A simple computer that marries the mind-boggling computing power of quantum mechanics with the ease of manipulating light has been built by researchers at the University of Rochester. The device ...

AI models are power hogs. As the algorithms grow and become more complex, they’re increasingly taxing current computer chips. Multiple companies have designed chips tailored to AI to reduce power draw ...

In 2009, Jeremy O'Brien, a professor at the University of Bristol, published a research paper describing how to repurpose on-chip optical components originally developed by the telecom industry to ...
