Foxconn collaboration examines light sources for optical connections in data centers and high-performance computing

LINKÖPING, Sweden, Nov. 12, 2026 /PRNewswire/ — Polar Light Technologies AB (“Polar Light”), a global leader in MicroLED and NanoLED technology, today announced its first cooperation agreement related to MicroLED optical interconnect. The collaboration with Foxconn Technology Co., Ltd. will focus on green MicroLED at 5 µm, which is consistent with the first range of MicroLED products currently in production via Polar Light’s manufacturing pilot line.

Optical interconnects use light to transmit data between computing components and systems.

“For years, Polar Light has demonstrated the advantages of our MicroLED technology in displays. The same fast, efficient, CMOS-integrated emitters can help AI data centers overcome interconnect limits,” said Oskar Fajerson, CEO of Polar Light Technologies. “Alongside our continued display work, working with Foxconn gives us a great opportunity to apply our MicroLED technology to a new application area – optical interconnect. Our next-generation pyramidal architecture is designed to reduce power consumption and cost.”

“We are excited about the opportunity to collaborate with Polar Light Technologies and look forward to exploring the potential of its MicroLED technology,” said Yen-Jen Pan, CEO of Foxconn Technology Co., Ltd. “We also look forward to supporting Polar Light in bringing its innovative technologies to advanced ICT applications.”

Polar Light’s next-generation MicroLED 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.

Advantages of Polar Light’s MicroLED emitters for optical interconnect include:

• High density: Polar Light’s ability to produce green MicroLEDs with µm, and even sub-µm, 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 MicroLEDs with CMOS backplanes.

About Polar Light Technologies

Headquartered in Linköping, Sweden, Polar Light Technologies is the leading developer of next-generation MicroLED technologies. 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 NanoLEDs, while the reduced piezoelectric effect shortens carrier decay times – providing key advantages for high-speed optical interconnects.
