As artificial intelligence scales, computation is no longer the only challenge. This briefing examines how communication, networking and photonics are emerging as critical constraints that may shape the future performance, efficiency and infrastructure of AI systems.
The Physics of Intelligence

Why the future of AI may depend on light, energy and communication
Artificial intelligence is often presented as a software revolution. Yet beneath every AI model lies a physical infrastructure of chips, networks, energy systems and increasingly, light.
Artificial intelligence is transforming economies, industries and societies. Most discussions focus on algorithms, computing power and increasingly capable models. But as AI systems continue to grow, attention is beginning to shift towards the infrastructure that makes intelligence possible.
Moving data has become almost as important as processing it. AI clusters contain thousands of processors that constantly exchange information. The speed, efficiency and energy consumption of those connections may increasingly determine the future performance of artificial intelligence itself.
This series explores the physical foundations of AI. From photonics and semiconductor ecosystems to energy systems and communication networks, it examines how the future of intelligence may depend not only on software, but on the technologies that enable information to move through the modern world.
Intelligence may be digital. Its foundations remain physical.
As artificial intelligence, cloud infrastructure and advanced communications continue to scale, photonics is emerging as a critical enabling technology. This briefing explores how PhotonDelta is helping build a European ecosystem that could become strategically important to the future of digital infrastructure.
Integrated photonics is moving from research laboratories into commercial deployment. This briefing explores why manufacturing capacity may become one of Europe’s most important strategic assets and how SMART Photonics is helping transform scientific innovation into industrial capability.
As artificial intelligence and cloud computing continue to scale, communication networks are becoming a critical part of digital infrastructure. This briefing explores how EFFECT Photonics is helping address the growing challenge of moving information efficiently through increasingly complex AI and cloud environments.
Behind many of the technologies shaping the future of computing stands a different type of institution. This briefing explores how imec has become one of Europe’s most important research infrastructures for semiconductors, photonics, AI hardware and advanced packaging technologies.
Behind many of Europe’s most advanced technologies stands an institution few people know. This briefing explores how CEA-Leti helps transform breakthroughs in semiconductors, photonics, sensing and artificial intelligence into technologies that may shape future industries.
Tyndall National Institute operates at the intersection of photonics, semiconductors and advanced materials. This briefing explores how research, talent and knowledge transfer help transform scientific discoveries into technologies that eventually shape artificial intelligence, communications and next-generation digital infrastructure.
