Meta description: Discover how photonic computing and optical NPUs use light to accelerate AI, reduce chip heat, improve data-center efficiency, and reshape the future beyond traditional GPUs.
Executive Summary
Photonic computing uses light—not just electricity—to move and process information. Optical neural processing units, or optical NPUs, are designed to accelerate the math behind artificial intelligence by sending photons through tiny on-chip waveguides, interferometers, modulators, and detectors. The value is easy to understand: more AI throughput, less electrical resistance, lower heat, and potentially much better energy efficiency for inference-heavy workloads. This technology will not replace GPUs overnight. However, it could become one of the most important upgrades for AI data centers as power use, cooling, and chip-to-chip bandwidth become major limits on AI growth.
