Amorphous Metal‐Sulphide Microfibers Enable Photonic Synapses for Brain‐Like Computing

In the pursuit of all-optical brain-like computing, optical axons and photonic synapses are demonstrated using metal-sulphide microfibers, which allow the generation and propagation of optical action potentials. This gives rise to an all-optical implementation of a number of interneuronal and intraneuronal communication protocols that underlie learning and cognition in the brain.
