China Optical Chip Breakthrough

Chinese scientists have created a low-cost method to mass-produce optical chips that are used in supercomputers and data centres, helping to reduce the impact of US sanctions.

The chips, or photonic integrated circuits (PIC), use photons – particles of light – to process and transmit information.


It is not that simple. Any flaw makes for a defective chip. The gates are hard to construct. Costs could go much higher regardless of the cost of materials.
