For decades, we’ve moved data using electrons through copper wires. But electrons generate heat, and heat is the enemy of the AI era. Enter Photonics Computing, where light (photons) replaces electricity for data transmission and, increasingly, for computation itself.
By 2026, optical interconnects have become standard in high-end data centers. Photonic chips can move data at the speed of light with almost zero heat loss, allowing for denser, faster clusters that were previously impossible due to thermal limits. While we aren’t all using “light-based laptops” yet, the backbone of the internet and the massive AI training clusters of 2026 are now powered by the laser, not the wire.
