Space-Based Optical Networks: With the surge in satellite mega-constellations, laser-based Inter-Satellite Links (ISL) have become the standard for high-speed, low-latency global internet, replacing slower radio-frequency (RF) links.
Photonic Quantum Computing: 2026 is a milestone year as companies like QuiX Quantum deliver the first commercial Universal Photonic Quantum Computers. Photons are favored for quantum work because they don't require the extreme near-absolute-zero temperatures that superconducting chips need.
CPO for AI Clusters: Companies like NVIDIA have officially integrated optical engines directly onto the processor package (using TSMC’s COUPE platform). This reduces power consumption by ~35% and allows thousands of GPUs to communicate as a single "super-chip.
