The Speed of Light Meets Machine Learning: How Silicon Photonic Neural Networks Could Replace GPU Clusters

When AI training consumes entire power grids and takes weeks to complete, photonic processors offer a radical alternative: performing matrix operations at the speed of light. Recent breakthroughs demonstrate 100x speedup potential in neural network training using silicon photonic chips that replace electronic computation with optical interference patterns. This isn’t distant future tech—companies like Lightmatter and Intel are already prototyping photonic AI accelerators that could make today’s GPU farms look primitive.
