S‑CALe iIT is a European research project developing the next generation of self‑calibrating photodetectors — tiny, highly accurate sensors that measure light with exceptional precision. Building on the success of earlier self calibrating projects, this project extends the technology into the infrared range and integrates it directly into photonic chips.
The long‑term vision is an “NMI‑on‑a‑chip”: built‑in metrological accuracy inside the device itself. This enables simpler, more robust and more precise measurements in satellites, industry, healthcare and emerging photonic technologies.
Europe is investing heavily in photonics and chip technology. Demand is growing rapidly for miniaturised, reliable optical sensors used in climate monitoring, medical diagnostics, communication, quantum technology and more.
Today, metrology cannot provide on‑chip SI traceability. This gap slows innovation and increases costs.
S‑CALe iIT will change that by developing self‑calibrating photodiodes, extending predictable detector technology into the 900–1600 nm infrared range, and enabling traceability directly in photonic integrated circuits.
Justervesenet coordinates the project and leads the development of new metrological methods that bring SI traceability into compact, integrated systems.
By developing reliable, traceable optical standards, we support European industry, research and decision‑makers.
The project is coordinated by Justervesenet and brings together 17 partners from 12 countries.
