TSMC Bets On Unorthodox Optical Tech
TSMC is working with startup Avicena to produce microLED-based interconnects. The technology is designed to meet the high needs of communication among an increasing number of GPUs in a low-cost, energy-efficient way. AI clusters are facing unprecedented requirements - sooner or later, the copper wires that connect processors and memory within a single AI data rack will have to be replaced with optics. Avicena's approach is very unorthodox, but it is ideal for these short-distance applications.
