Ultrafast Low-Energy AI Hardware Using Light-Based Computing Chips

digitalPrototypeTRL 3Thin data (2/5)

Imagine a computer chip that uses light instead of electricity to think, making it incredibly fast and energy-efficient. Instead of standard switches, it uses a special material that acts like a dimmer switch for light, allowing the chip to be reprogrammed on the fly. It's like building a brain out of light-conducting glass that can change its own logic to solve different problems.
