Traditional computers use electrons flowing through silicon circuits to process information. Photonic computers use photons — particles of light — instead.
Light travels at 299,792 km/s in vacuum and doesn't generate heat like electrons do. This fundamental physics difference enables photonic processors to perform matrix operations (the core of neural networks) at unprecedented speeds with minimal energy loss.
Photonic chips use waveguides, modulators, and interferometers to manipulate light signals. Multiple light beams can pass through the same space without interfering, enabling massive parallelization impossible in electronic systems.
For AI, this matters because almost every modern model is built around large matrix operations. Photonic hardware is naturally good at these operations, so it can accelerate core AI workloads while using far less power than electronic accelerators.
The business impact is clear: lower infrastructure spend, higher model throughput, and better user experience at scale.
