The fundamental speed and energy bottleneck in modern computing is not the processor — it's data movement. Electrical interconnects between chips, between memory and compute, and within AI accelerators consume a disproportionate share of total system energy. This is the problem photonics addresses. **[Photonic Computing: Why Light-Based Chips Could Outpace Silicon](/node/1460)** explains how photonic integrated circuits route data as light instead of electrical signals, what the implications are for latency and bandwidth density, and where photonics is already deployed (optical transceivers in data centers) versus where it remains experimental (on-chip photonic computing, photonic matrix multiplication for AI inference). Companies like Lightmatter, Luminous Computing, and PsiQuantum are betting that photonic interconnects — and in PsiQuantum's case, photonic qubits for quantum computing — represent the next architectural inflection point. The physics is compelling; the manufacturing challenges in producing photonic chips at CMOS-compatible yields are significant. This piece works through both.
