From Lab to Light
Eindhoven’s Bet on the Next Chip Revolution
On the northern edge of the High Tech Campus in Eindhoven, cranes and concrete mixers now dominate a site that may help define Europe’s technological future. In a few years, the building rising here will house a facility unlike any other in the world: an industrial pilot line capable of producing photonic chips on 6-inch indium phosphide wafers.
The contrast is striking. Outside, heavy machinery pounds steel into the Dutch soil. Inside the future cleanrooms, when they open, engineers will work in near silence, manipulating structures smaller than a human hair so that light itself can carry information across microscopic circuits.
Behind this construction site lies an ambition far larger than the building footprint. Governments, research institutes and companies hope the project will help Europe reclaim a measure of technological independence in the global semiconductor race — and usher in a new generation of computing built not on electricity, but on light.
“We can no longer afford, as Europe, to depend on other continents for our most critical technologies. The battle for chips is the geopolitical battle of the 21st century. Eindhoven proves the Netherlands is not merely a spectator, but an architect of our own digital sovereignty.”

The new facility, part of the European PIXEurope initiative under the EU Chips Act, is designed to bridge a critical gap in the semiconductor world — the notorious space between laboratory breakthroughs and scalable industrial manufacturing.
For the Netherlands, it also marks a symbolic return. For the first time in more than four decades, the country is building a new chip production facility.
Computing With Light
To understand why governments and industry leaders are investing €150 million in this project, one first has to understand the promise of photonic chips.
Traditional computer chips process information using electrons moving through metal circuits. For decades, this electronic approach has powered everything from smartphones to supercomputers. But as artificial intelligence systems grow ever more demanding, the limits of electricity are becoming apparent.
Electric currents generate heat. They encounter resistance. They consume enormous amounts of energy.
Light behaves differently.
Photonic chips use photons — particles of light — to transmit and process data through microscopic waveguides etched into semiconductor material. Because photons travel faster and without electrical resistance, they can move vast quantities of information while consuming significantly less power.
“We are running into the physical limits of electricity. AI consumes enormous amounts of energy and data centers are overheating. Light is the only real way forward.”

In practical terms, that shift could transform several industries at once. AI data centers could transmit information between processors with far less energy. Telecommunications networks could move toward ultra-high-speed 6G connections. Medical diagnostics and sensing technologies could become dramatically more precise.
The concept is not new. Scientists have been exploring integrated photonics for decades. But until recently, the technology struggled to escape the confines of the research lab.
The Valley Between Discovery and Industry
In deep-tech sectors, scientists often speak of the “valley of death” — the point where promising research fails to become commercial reality.
For photonics, that valley lies between experimental prototypes and industrial production.
University laboratories can fabricate small numbers of chips using specialized equipment. But scaling those processes into reliable, repeatable manufacturing is vastly more complex. It requires industrial-grade cleanrooms, specialized fabrication equipment, standardized processes and a supply chain capable of supporting production.
This is precisely where the Eindhoven pilot line aims to intervene.
“The science behind photonics is solid, but the world is now asking us a different question: can this technology be produced at scale? The step from the laboratory to the factory is the most difficult phase in deep-tech. With PIXEurope we are not simply building a facility; we are laying the foundation for an industry that, within a decade, could be as commonplace as the electronic chip sector is today.”
Eelko Brinkhoff
CEO, PhotonDelta
The pilot line will allow companies and research groups to develop photonic designs and test them on industrial equipment capable of producing thousands of wafers per year. It effectively creates a bridge between research institutes and commercial chip foundries.
The facility will focus on indium phosphide (InP) technology, a semiconductor material particularly suited for photonics because it can generate and manipulate laser light directly on a chip.
That capability gives the Netherlands a distinct advantage.
Eindhoven’s Semiconductor Ecosystem
Few places in Europe have a semiconductor cluster as concentrated as Eindhoven.
Within a few kilometers of the new pilot line sit some of the most influential institutions in global chip technology: the High Tech Campus, Eindhoven University of Technology, research organization TNO and companies such as SMART Photonics.
Perhaps most famously, the region is also home to ASML, the Dutch company that builds the extreme ultraviolet lithography machines required to produce the world’s most advanced chips.
Over decades, this ecosystem has grown into a dense network of engineers, suppliers, startups and research labs — a cluster sometimes described as “the smartest square kilometre in Europe”.
The new photonics pilot line aims to reinforce that position.
By connecting university research, startups and industrial partners in one shared manufacturing environment, the project hopes to accelerate innovation cycles and reduce the time required to move from experimental design to market-ready technology.
But Eindhoven’s ambitions extend beyond regional economic development.
They are increasingly tied to geopolitics.
Europe’s Semiconductor Strategy
In recent years, semiconductor supply chains have become a focal point of global power politics.
The COVID-19 pandemic exposed the fragility of chip supply networks. Tensions between the United States and China have further highlighted the strategic importance of semiconductor technology. Meanwhile, Taiwan’s dominance in advanced chip manufacturing — through companies such as TSMC — has raised concerns about geopolitical vulnerability.
In response, the European Union launched the EU Chips Act, a multibillion-euro strategy aimed at strengthening semiconductor research, production and supply chains within Europe.
“Europe must become the factory of tomorrow’s technologies.”
Thierry Breton
European Commissioner for the Internal Market
Architect of the EU Chips Act
The Eindhoven photonics facility represents one of the initiative’s most specialized components. Rather than competing directly with massive silicon fabs in Asia, Europe hopes to establish leadership in emerging technologies where it already has strong research capabilities.
Integrated photonics is one of those fields.
Several European institutes — including imec in Belgium and CEA-Leti in France — are already recognized leaders in the technology. Eindhoven’s role is to push that research toward scalable industrial manufacturing.
If successful, the region could become the center of a new photonic chip supply chain spanning multiple European countries.
The Promise of a New Computing Paradigm
Advocates of photonics believe the technology could represent the next major evolution in computing architecture.
The reason lies largely in the demands of artificial intelligence.
Modern AI systems rely on enormous volumes of data moving between processors, memory and networking hardware. In many cases, the biggest bottleneck is not computation itself but the movement of information between chips.
Optical communication — essentially using light instead of electricity — could drastically increase bandwidth while reducing energy consumption.
Industry analysts estimate that optical interconnects could reduce data-transport energy costs in large data centers by an order of magnitude.
If that proves true, photonic chips could become a key enabling technology for the next generation of AI infrastructure.
And that possibility explains why governments are paying attention.
Economic Potential — and Uncertainty
For the Netherlands, the project also represents an economic opportunity.
The facility itself will initially employ several dozen specialists, but its broader impact could be much larger. By providing shared manufacturing infrastructure, the pilot line may enable new startups, attract international investment and accelerate the commercialization of photonic technologies.
Still, the scale of the investment raises questions.
In the global semiconductor industry, €150 million is modest. Companies such as Intel, Samsung and TSMC routinely invest tens of billions of euros in new fabrication plants.
Some analysts therefore view the Eindhoven facility less as a factory and more as an experimental platform — a stepping stone toward future industrial capacity.
Even within the Dutch technology community, there is awareness that success is far from guaranteed.
“The ecosystem in Eindhoven is unique in the world, but we must be careful not to price ourselves out of the market through a shortage of talent or a lack of long-term vision. Technology waits for no one. If we do not build this industry here, it will emerge in the United States or China.”

A Strategic Bet on Light
Back at the construction site in Eindhoven, the cranes will soon give way to cleanrooms, precision machinery and researchers in sterile suits.
The environment inside the future facility will be radically different from the noise and dust of the building phase. In ultra-controlled rooms where vibrations and dust particles are carefully managed, engineers will attempt to guide photons through structures invisible to the naked eye.
If they succeed, those beams of light could form the backbone of the next generation of digital infrastructure.
For Europe, the stakes go beyond scientific curiosity.
They touch economic resilience, technological sovereignty and the continent’s ability to compete in an increasingly technology-driven world.
The building rising in Eindhoven may not match the scale of the massive semiconductor fabs of Asia or the United States. But its ambition is different.
Rather than replicating yesterday’s chip industry, it aims to help invent the next one — one where the fundamental unit of computation is not the electron, but the photon.
