Photon-driven synapse advances low-power neuromorphic systems
A photon-modulated synaptic device based on a rare-earth-doped long-afterglow crystal facilitates excitatory (UV-induced) and inhibitory (near-infrared induced) plasticity. This schematic depicts the excitatory impulse with luminescence as the optical output. Credit: Y. Yan et al.

Modern artificial intelligence systems rely on moving large amounts of data between memory and processors, a design that limits speed and increases energy use. The human brain works differently: it combines memory and computation within synapses, allowing fast, efficient learning and perception. Replicating this approach in hardware is a central goal of neuromorphic computing, especially for tasks like vision, where most real-world information is gathered and processed.
