Researchers at the University of Sydney have built a nanophotonic chip prototype that performs artificial intelligence calculations using light instead of electricity. The experimental device ...

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.

Micro LED CPO architectures substantially lower energy consumption per transmitted bit, reducing total power consumption by up to nearly 20 times to approximately 1.6W ...

Artificial intelligence is consuming enormous amounts of energy, but researchers at the University of Florida have built a chip that could change everything by using light instead of electricity for a ...

A new academic review argues that artificial intelligence (AI) could help cities dim the lights intelligently, cutting both energy consumption and light pollution without compromising visibility or ...
