Photonic AI Chip Processes Data at Light Speed

Australian researchers have developed an ultra-compact photonic AI chip that performs calculations using light at the speed of light. This nano photonic chip prototype, built at the University of Sydney, could play a significant role in developing more energy-efficient AI hardware. Unlike traditional computer chips that use electricity and generate heat, this chip uses light, which travels without electrical resistance. The nanostructures within the chip automatically perform calculations as light passes through them. The prototype performs calculations on a picosecond timescale and was trained to classify over 10,000 biomedical images with approximately 90% to 99% classification accuracy. This technology offers a pathway to sustainable AI infrastructure capable of supporting the growing demands of computing without proportional increases in power consumption. The research demonstrates how AI models can be designed into nanoscale photonic structures that manipulate light to perform the mathematical operations required for machine learning.
