“We industrialized microLED arrays at scale with EVIYOS™ for highly pixelated automotive forward lighting. As the leader in Digital Photonics, we are now leveraging this expertise to tackle a key bottleneck of AI infrastructure the power required for data links between and within AI server racks,” said Aldo Kamper, CEO of ams OSRAM. “This achievement positions us strongly in a high growth segment of AI infrastructure.”
Outstanding Efficiency for AI data-center connectivity
The new microLED array prototype leverages a proprietary epitaxy stack and delivers:
• Cut-off frequency >1 GHz;
• Energy consumption below 2 pJ/bit;
• Massively parallel, short reach optical IO paths.
These characteristics directly address the interconnect bottleneck emerging in modern AI compute architectures, where data movement increasingly dominates system power budgets.
From award-winning EVIYOS™ to AI infrastructure optical interconnects
ams OSRAM microLED leadership is rooted in EVIYOS™, the world’s first high-volume automotive micro-emitter array. Delivering 25,600 individually addressable pixels, each approximately half the width of a human hair, combined with a CMOS driver chip in a compact package. This unique microLED - CMOS integration - a textbook example of Digital Photonics - was recognized with the German Future Prize as “Digital Light” established the company’s industrial-scale capabilities and has since demonstrated exceptional robustness in series production vehicles.
The same core technology now forms the basis for optical IO components targeting AI servers and rack level communication.
Proven micro-emitter technology for optical data communication
For optical interconnects, the fabrication process is similar to that used for automotive matrix emitters, with one key difference: while EVIYOS™ uses monolithic arrays, data center applications use singulated microLEDs. These emitters are diced from the wafer and mounted on a substrate, so each device couples to its own fiber optic channel in a multi-channel fiber optics cable. The substrate can then be assembled onto a target CMOS wafer for system integration.
Due to their extremely small footprint, microLED based transceivers can achieve very high bandwidth density. Individual emitters support per lane data rates of ≥3.0 Gbit/s at energy levels below 2 pJ/bit over a full 10 meter link, while meeting industry bit-error-rate specifications below 10⁻¹⁵.
Replacing a single ultra-high-speed line with hundreds of parallel channels in a slow-and-wide architecture offers multiple advantages for AI infrastructure:
• Reliability microLED based optical interconnect systems can include redundant channels, enabling graceful degradation and rapid replacement of faulty emitters.
• Efficiency in a slow-and-wide architecture, power consumption is significantly reduced versus ultra‑high‑frequency laser transmitters typically used in internet backbone applications. Lower power also reduces heat, providing valuable thermal headroom for data‑center operators.
• Simplicity microLED‑based interconnects are inherently parallel. They eliminate the complex and costly serialization/deserialization steps required by fast‑and‑narrow architectures.
From Prototype to Product Development
With the successful adaptation of its EVIYOS™ base technology to the needs of data‑communication markets, ams OSRAM is now transitioning rapidly into the product‑development phase fully aligned with the Digital Photonics strategy announced on 05 February 2026.
