‘A single optical fiber’: Scientists build a silicon-less computer that use light waves and surpasses existing systems for classification — could this be the ultimate AI CPU?

In an era where the ecological footprint of large-scale AI systems is increasingly being scrutinized, a team of international scientists has developed a potentially game-changing new solution. 

The team, led by Prof. Mario Chemnitz and Dr. Bennet Fischer from Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, has built a computer that uses light waves instead of silicon, and it’s all done through a single optical fiber.
