Researchers at Oregon State (OSU) and Baylor universities have significantly cut the energy consumption of photonic chips used in datacenters and supercomputers.

The technique offsets photonic chip-degrading temperature variations, potentially reducing the energy required to regulate temperature by a factor of more than 1 million.

OSU's John Conley explained, "We were able to make working prototypes that show temperature can be controlled via gate voltage, which means using virtually no electric current."

Conley said this innovation will help to increase the speed and power of datacenters "while using less energy so that we can access ever more powerful applications driven by machine learning, such as ChatGPT, without feeling guilty."
