Let There Be Light: Europe Bets Big on Owning Its Photonic-Chip Future

Inside Torre Glòries - the bullet-shaped tower that lords over Barcelona's 22@ innovation district - the view on Thursday was of a Mediterranean city drenched in light. Fitting, because the engineers, executives, and policymakers packed into the room had come to talk about exactly that: light and Europe's determination to build a chip industry it actually owns.

The occasion was PIXEurope Connect, the first "industry ecosystem building day" for PIXEurope - a roughly €400 million pan-European pilot line for photonic integrated circuits (PICs) that runs through 2030 and bills itself as the world's largest publicly funded photonics initiative. Coordinated from Barcelona by ICFO, the Institute of Photonic Sciences, and co-funded by the EU's Chips Joint Undertaking, it knits together some 20 research institutions across 11 countries. Interestingly, Germany is going its own way with a large photonics and quantum infrastructure in and around Munich. Switzerland, not an EU member state, has a rich history and a proliferation of photonics companies, but is not a direct participant in this ecosystem.

Thursday, May 21, 2026, was the day a now-supercharged European ecosystem stopped being a press release and started shaking hands with the companies meant to turn it into products.

If silicon chips are the brains of the digital age, photonic chips are its nervous-system upgrade: instead of shuttling information with electrons, they move it with photons - particles of light - which travel faster, run cooler, and consume far less power. That has gone from a laboratory curiosity to an industrial necessity almost overnight, because the technology most hungry for it is the one currently eating the world. "Now the demand for photonic devices and systems is really driven by AI and data centers," says ICFO's Valerio Pruneri, the pilot line's director. Inside those data centers, the copper wiring that links AI chips is expected to give way to light within about three years - one reason the semiconductor market is tipped to double over the next five.

Here is the subplot that gave the day its edge. Europe consumes roughly twice as much in electronics as it produces, even as the global semiconductor market marches toward €1.6 trillion by 2030. The continent more or less wrote the early textbook on integrated photonics - and is now watching others sprint ahead. Over the past two decades, China's share of the photonics market has ballooned from around 10% to more than 30%, while Europe and the United States each sit at around 15%. Tellingly, Beijing leaned into photonics precisely because Washington's export controls choked its access to advanced silicon. Squeezed between the two, Europe has evidently decided it would rather build than beg.

The fight Europe is picking
What made the room crackle was how candid it got. From the floor came the uncomfortable question everyone was thinking: where is Europe's volume-manufacturing champion? Datacom and telecom, the biggest photonics markets, are dominated by the US and Asia, where Europe barely registers. Pruneri's answer doubled as the strategy - don't try to out-scale Asia. Win instead on distinctive technology, transfer it fast to Europe's startups, SMEs, and spin-offs, and target the specialized and defense markets that move in the thousands-to-millions of units rather than the 300-million-unit commodity race for data-center optics.

Nobody pretended it would be easy. The real bottleneck is the leap from lab to fab: photonics still crawls where chipmaking flies - a lithography scanner in a CMOS semiconductor fab can pattern roughly 200 wafers an hour; photonics is orders of magnitude slower - and the field has yet to settle on common standards, so almost everything is still built bespoke. Then there is the perennial European heartbreak: brilliant startups getting bought and their know-how shipped offshore. The counterpoint on display was that the buying can run the other way, too - Nokia's $2.3 billion acquisitions of US optical leader Infinera, in addition to its 2016 acquisition of Bell Labs (where the laser was invented), shows a European champion writing the check for a change.

From lab bench to factory floor
PIXEurope's fix is refreshingly unglamorous: shared plumbing. It aims to be the world's first open-access PIC ecosystem, offering everything from collaborative R&D, where customers co-create the technology, to prototyping runs where they simply place an order - all through a single gateway with an assigned account manager. It spans the full value chain and every major material, from silicon and silicon nitride to indium phosphide (in chronic short supply) and thin-film lithium niobate, across a spectral range from ultraviolet to mid-infrared, with programmable photonics aimed squarely at AI.

And the flywheel is already turning. Cited from the stage were bets that suggest momentum: ams Osram's €200 million-plus photonics push in Austria, programmable-chip maker iPronics wiring up AI interconnects, quantum-security firm Quside, the Dutch indium-phosphide foundry SMART Photonics, and a graphene-transceiver venture spinning up a line near Milan. PIXEurope even has a people plan - training 1,000 workers by 2028, including technicians reskilled from industries such as automotive, not just PhDs.

Why the money is watching
For investors, the arithmetic is hard to ignore. The integrated photonics market is forecast to grow by more than 350% over five years, reaching roughly €65 billion by 2031. The Chips Joint Undertaking behind PIXEurope - led by executive director Jari Kinaret - is mobilizing nearly €11 billion in combined public and private funding. The timing is no accident: a Chips Act 2.0, expected within weeks, is set to name photonics as an explicit objective, with a new European Competitiveness Fund to follow in 2027. The smart question is no longer whether photonics scales, but who captures the value when it does.

As the sun dropped behind Torre Glòries, the metaphor practically wrote itself. Europe has decided it does not want to import its light. After years of watching the chip wars from the sidelines, the continent that gave the world several of photonics' foundational ideas is finally putting infrastructure, money, and - crucially - a sense of urgency behind them. Barcelona didn't just host a conference on Thursday. It hosted a statement of intent.
