The AI boom is hitting a physical limit, with data centre chips, cables, and components struggling to manage growing data volumes and processing speeds. A new wave of photonics startups across Europe is emerging to solve this bottleneck using light-based technologies. These companies are developing optical interconnects, high-speed transceivers, and AI-optimized photonic processors to replace traditional electronics.
The sector has attracted significant funding, with several startups reaching unicorn status and collectively drawing hundreds of millions in investment. Investors are betting that photonic computing will deliver the performance-per-watt needed to sustain AI infrastructure growth. The mapping exercise highlights 74 promising ventures, from established players to early-stage innovators, spanning the continent.
These startups are working on everything from optical memory to free-space communication, aiming to keep pace with AI's insatiable computational demands. The technology promises lower latency, reduced energy consumption, and higher bandwidth than conventional copper-based systems. As data centres face escalating power and cooling costs, photonics offers a potential path forward for next-generation computing architecture.
