For decades, chips have relied on invisible infrared light to move data. A new shift is emerging, where visible light introduces precision, sensing and interaction—moving technology beyond transport toward a deeper connection with the physical world.
The Color of the Next Chip
Why visible light is redefining the future of chips—and Europe’s position in the next technological shift
A quiet shift is underway in chip technology, where light itself—rather than electrons—begins to define performance and possibility.
For decades, the digital world has been built on invisible light, operating in infrared wavelengths designed for data transport. But a new phase is emerging. As researchers explore blue and visible light on chips, the focus shifts from speed alone to precision, sensing and interaction with the physical world. This series examines how that transition unfolds—and why it may redefine not just technology, but Europe’s strategic position in it.
The next generation of chips is not limited by code, but by materials. As photonics advances, the challenge shifts to integrating fundamentally different substances—where even atomic mismatches can determine whether light is guided or lost.
For the first time, photonics brings light generation, guidance and coupling together on a single chip. This shift transforms a long-standing experiment into a scalable platform—marking a turning point in how chips interact with the physical world.
As photonics moves from lab to platform, chips begin to sense, measure and interact with the physical world. From healthcare to quantum systems, this shift marks a transition from processing information to perceiving reality.
