If you haven’t spent a morning in Eindhoven, sipping bitter coffee while watching engineers walk between labs with fibre reels tucked under their arms, you haven’t felt how quietly intense this place is. It’s not showy like Silicon Valley. It’s lean, dense and a little Dutch about it, something pragmatic, cooperative and stubbornly focused on turning optics and light into exportable industry.
Eindhoven calls itself Brainport for a reason because this is where applied photonics meets Dutch industrial know-how. You’ll find universities, corporate R&D facilities, start-ups, and shared pilot fabs within cycling distance. If you want to understand how photonics evolves from a whiteboard idea to a product on a factory conveyor, this is a great place to come and listen.
What does “Photonics Valley” actually look like?
When people invent nicknames like “Photonics Valley,” they usually mean one thing: a dense geography where research, suppliers, and customers co-locate, so momentum becomes contagious. That’s precisely what Eindhoven has built. The region hosts PhotonDelta, a non-profit ecosystem builder that stitches universities, fabs and companies together to scale photonic-chip production and applications across Europe. PhotonDelta runs roadmaps, coordinates pilots and helps companies find manufacturing partners; it’s one reason Eindhoven punches well above its population weight.
You can feel it on campus, as spin-offs from prominent firms and universities nestle beside specialist tool vendors, packaging companies, and system integrators. That proximity shortens feedback loops, allowing an optical sensor team to iterate with a packaging firm and a potential buyer in days, not quarters. For photonics, where packaging and coupling losses make or break a product, that speed is gold.
Why Philips, ASML, and the Brainport network matter here
Eindhoven’s photonics success has grown from decades of industrial roots. Philips’ profound R&D legacy seeded talent, and ASML, which is also a global giant in lithography equipment, now traces important early links to the region’s optics and semiconductor cluster. Those corporate ancestors left more than just buildings, as they engineered supply chains, supplier capabilities, and a managerial DNA that favours industrial scale. Recent corporate commitments from companies such as ASML and NXP, among others, contributing to regional infrastructure funds, demonstrate how large incumbents continue to underwrite the ecosystem’s expansion.
That matters because photonics isn’t just clever lab work. You need tools, optics suppliers, clean rooms and a local logistics network that understands tight tolerances. Big industry players create the market pull that enables small photonics companies to graduate from lab demonstrations to paying customers.
The practical advantage of having PhotonDelta, Holst Centre and shared piloting.
Witness the Dutch model in action with PhotonDelta and the Holst Centre. PhotonDelta orchestrates the end-to-end value chain for photonic chips, while the Holst Centre translates early research into real-world applications in sensing and flexible electronics. This practical approach, along with funding mechanisms that support pilot lines and packaging R&D, is a real asset, reducing the common problem of ‘you built it but can’t make money with it’ that many hardware startups face. The region’s focus on manufacturing readiness and packaging is why more spin-offs survive here than in many other European cities.
Here, the Dutch approach quietly differs from louder ecosystems. Public and private actors collaborate to create shared industrial capacity, rather than duplicating expensive equipment in 20 separate labs. This unique strategy is a testament to the region’s commitment to efficiency and resource optimization.
Spin-offs you’ll actually meet on the street and what they teach you
Walk through High Tech Campus and you’ll encounter companies that are small in headcount but big in technical leverage. Startups making silicon nitride waveguides, specialists in photonic packaging, and sensor firms targeting health and mobility. They are engineering firms that sell into larger OEMs and supply chains. That incrementalism is how deep technology builds durable businesses, where a string of B2B wins, not one viral consumer hit, is achieved.
Through a critical lens
I read numerous breathless pieces that frame Eindhoven as “the next Silicon Valley of light.” That sells headlines but flattens reality. Photonics is exceptionally hardware-intensive and sensitive to supply chains; you can’t scale packages like software. Additionally, the region’s strength lies not in viral growth but in industrial depth, which includes dozens of pragmatic, incremental bets rather than a single breakout consumer app. If you want to capture the real lesson, don’t look for a single superstar; instead, look for the scaffolding, such as pilot fabs, packaging specialists, and contract manufacturers, that enable many small firms to come together and form an industry.
How to visit, what to see and who to meet
If you’re curious, start with a guided visit to High Tech Campus Eindhoven and a stop at PhotonDelta or Holst Centre (they host public events and demo days). Join a Delta Dialogues session if timing allows, and you’ll hear roadmaps for automotive sensing, telecom photonics and health monitoring. Talk to packaging houses and system integrators over coffee, they’ll explain why a seemingly trivial connector can make or break a sensor product. And if you have time, drive to Veldhoven to see where larger supply chains (and ASML’s influence) still shape the region’s engineering DNA.
Why you should care (and possibly invest your travel budget)
Suppose you care about industrial innovation, supply chain sovereignty, or the next generation of sensors and telecommunications. Eindhoven matters. The region is quietly building the manufacturing backbone for photonic chips and integrated optical systems, which are the same components that will be inside future medical sensors, LIDAR units, and quantum devices. If you want to see how hardware-scale ecosystems form, this is one of the best classrooms in Europe.
