Fiber optic cables have a bottleneck problem. Although they’re capable of transporting encoded data at the speed of light, translating the encoded data into understandable information often requires slower, much more energy-hungry equipment. Building off of previous innovations in a field known as passive neural networks, however, a team at […]
