Polar Light achieves nano-scale LED, paving way to next-gen micro-LED/nano-LED devices
At SPIE Photonics West 2026 in San Francisco, CA, USA (20–22 January), Polar Light Technologies AB — which stems from research by founder professor Per-Olof Holtz and his team at Linköping University (with support from Sweden’s innovation agency Vinnova) — has announced that it has produced its first series of nano-scale LEDs. The firm says that this illustrates the flexibility of its patented pyramidal architecture, developed without requiring the traditional etching process.
Over the last several months, Polar Light has produced a series of electrically excited indium gallium nitride (InGaN) nano-LEDs, measuring 500nm and smaller, which are built using the same monolithic architecture as Polar Light’s existing micro-LED platform. This new process enables the firm to scale its technology to significantly smaller dimensions without compromising performance or efficiency.
“Reaching nano-LED scale without sacrificing LED performance or production capability is a major milestone for the industry,” claims CEO Oskar Fajerson. “Nano-LEDs, in combination with our roadmap toward monolithic RGB, will enable the next generation of ultra-small, monolithic full-color displays.”
In spring 2025, Polar Light demonstrated its first public prototype at Display Week. In January 2026, the firm announced a new €5m+ funding round that will enable the firm to bring its first products to market in late 2026.
