Polar Light signs first optical interconnect agreement leveraging micro-LED technology platform
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 its first cooperation agreement related to micro-LED optical interconnect. The collaboration with Foxconn Technology Co Ltd will focus on green micro-LED at 5µm, which is consistent with the first range of micro-LED products currently in production via Polar Light’s manufacturing pilot line.
“For years, Polar Light has demonstrated the advantages of our micro-LED technology in displays. The same fast, efficient, CMOS-integrated emitters can help AI data centers overcome interconnect limits,” says CEO Oskar Fajerson. “Alongside our continued display work, working with Foxconn gives us a great opportunity to apply our micro-LED technology to a new application area - optical interconnect. Our next-generation pyramidal architecture is designed to reduce power consumption and cost,” he adds.
Polar Light’s next-generation micro-LED technologies represent a leap forward in the types of light sources available to power the coming wave of high-performance connectivity solutions for data centers, AI accelerators and high-performance computing.
Polar Light says that advantages of its micro-LED emitters for optical interconnect include:
- High density: Polar Light’s ability to produce green micro-LEDs with micron, and even sub-micron, LED dimensions for high LED-density requirements.
- Faster data rates: Proven capabilities to reduce the piezoelectric effect by 40%, compared with conventional, planar InGaN LEDs, enabling higher data transfer rates.
- More efficient coupling: A Lambertian light lobe for high in-coupling efficiency into an optical fiber.
- Proven CMOS integration: The ability to integrate Polar Light’s pyramidal micro-LEDs with CMOS backplanes.
Polar Light’s unique architecture uses InGaN-based pyramidal structures grown without etching. This enables full RGB emission within the same material system and lays the foundation for nano-LEDs, while the reduced piezoelectric effect shortens carrier decay times. providing key advantages for high-speed optical interconnects, it is reckoned.
